Title of the invention: Tool for designing an electronic circuit, electronic housing, control unit and associated method

[0001] • Technical field of the invention

[0002] The present invention relates to the technical field of electronic circuit design tools, and more particularly to design tools enabling the numerical simulation of said electronic circuit. • State of the art

[0003] Educational games simulating an electronic circuit, such as the one described in US patent 11,806,632 B2, are known. This type of game comprises a game board and game pieces. Each game piece is a fictitious representation of an electronic function; that is, the game piece is devoid of electronic components. Each game piece has an identification code printed on its underside. Several game pieces are arranged on squares on the surface of the game board to form a fictitious electrical circuit. The game board is equipped with sensors for reading the identification code of each of the game pieces arranged on its surface. The game board also incorporates a microprocessor capable of simulating the fictitious electrical circuit.The game board also includes diodes which, through light displays on its surface, present the user with a fictional visualization of the operation of the fictional electrical circuit.

[0004] This type of game is particularly well-suited for introducing young children to electronics. However, it has many limitations that make it unsuitable for use as a design tool. First, this type of game is limited to simulation and does not allow experimentation with real electronic components. Furthermore, the game board has a predefined number of spaces, thus limiting the number of possible simulated fictitious electronic circuits. Finally, the user's analysis of the operation of the simulated fictitious electronic circuit is limited to observing a play of light on its surface. It is therefore impossible for the user to take measurements of electronic characteristics or to interact with the dimensional values ​​of the electronic components.

[0005] Faced with this situation, the invention aims to provide a design tool for an electronic circuit that allows both numerical simulation and real experimentation of an electronic circuit without limits in the number of electronic functions constituting it. • Disclosure of the invention

[0006] A first aspect of the invention relates to a tool for designing an electronic circuit comprising: • at least two electronic control units, • a control unit,

[0008] Thus, the design tool of the invention allows both the digital simulation and the actual testing of an electronic circuit. Indeed, the integration of a functional electronic circuit into each of the electronic packages allows for real-world testing of the resulting overall functional electronic circuit. The control unit, in turn, provides a digital simulation of the overall functional electronic circuit. Furthermore, the design tool of the invention has no limitations in the number of usable electronic functions. In fact, it is possible to interconnect an unlimited number of electronic packages.

[0016] One advantage is to allow the electronic boxes to communicate with the control unit, for example to identify themselves, to position themselves within the overall functional electronic circuit, or to modify the dimensional value of an electronic characteristic of their electronic function.

[0017] According to one embodiment: • at least one electronic control unit includes an adjustment device configured to modify the value of an electronic characteristic of the functional electronic circuit of said electronic control unit, • the control unit is configured to control said adjusting element so as to modify the value of said electronic characteristic so that said value is equal to a predetermined value.

[0018] One advantage is to allow modification of the value of an electronic characteristic of the functional electronic circuit of said electronic box.

[0019] Another aspect of the invention relates to an electronic housing for a design tool according to the invention, remarkable in that said electronic housing comprises a functional electronic circuit configured to transform a functional input signal into a functional output signal, and in that it is configured to interconnect with other electronic housings so as to form an overall functional electronic circuit by electrical connection of the functional electronic circuit with those of said other electronic housings.

[0020] Such an electronic box can be interconnected with an upstream electronic box and / or a downstream electronic box. Thus, it is possible to create a circuit A complete functional electronic circuit can be created from as many electronic packages as needed. Furthermore, integrating a functional electronic circuit into each package allows for real-world experimentation with the resulting complete functional electronic circuit.

[0021] Another aspect of the invention relates to a control unit for a design tool according to the invention, said control unit being notable in that it is configured to generate a digital model of an overall functional electronic circuit formed by an electrical connection of functional electronic circuits of at least two interconnected electronic packages.

[0022] Such a control unit makes it possible to generate a digital model of the real overall functional electronic circuit.

[0023] Another aspect of the invention relates to a method for designing an electronic circuit, remarkable in that it comprises the following steps: • a) provide at least two electronic enclosures, each comprising a functional electronic circuit configured to transform a functional input signal into a functional output signal, • b) interconnect said at least two electronic enclosures so as to form a complete functional electronic circuit by electrically connecting the functional electronic circuits of said at least two electronic enclosures, • c) generate a digital model of the overall functional electronic circuit.

[0024] Thus, the design method of the invention makes it possible to both digitally simulate and actually test an electronic circuit. Indeed, the steps of supplying and interconnecting electronic packages, each incorporating an electronic circuit, make it possible to obtain an overall functional electronic circuit that can be actually tested. The digital modeling step, for its part, makes it possible to obtain a digital simulation of the overall functional electronic circuit. Furthermore, the design method of the invention has no limitations in the number of usable electronic functions. Indeed, it is possible to supply and interconnect an infinite number of electronic packages.

[0028] A first aspect of the invention relates to a tool for designing an electronic circuit 1, hereinafter referred to simply as "design tool 1". "Designing an electronic circuit" means all the processes leading to the realization of a final electronic circuit. These processes may be intellectual and industrial, or of any other form suitable to a person skilled in the art. The design tool 1 can be used in a professional setting for the design of an electronic circuit intended for use, particularly commercialization. The design tool 1 can also be used in an educational setting for the learning and / or assessment of students.

[0029] The design tool 1 comprises at least two electronic housings 2. An electronic housing 2 may have a parallelepiped shape as in the embodiment examples shown in Figures [Fig. 1], [Fig. 2], [Fig. 3], [Fig. 4], [Fig. 5], [Fig. 6], and [Fig. 7]. In alternative embodiments, the electronic housing 2 may have the shape of a prism, a cylinder, or any other shape suitable to those skilled in the art. The electronic housing 2 may have a width between 1 cm and 2.5 cm, a length between 1 cm and 2.5 cm, and a height between 5 mm and 40 mm. Preferably, the electronic box 2 has dimensions that allow it to be handled by hand.

[0030] An electronic enclosure 2 comprises a functional electronic circuit. This circuit is configured to transform an input functional signal into an output functional signal. The transformation of the input functional signal into an output functional signal may, in particular, correspond to an electronic function. This function may be a digital electronic function. For example, it may be a diode, an oscillator, a logic gate of the type "true", "false", "true or false", "and", "or", "not", "not-and", "not-or", "exclusive-or", "coincidence", "implication", or any other digital electronic function suitable to those skilled in the art. The electronic function may also be an analog electronic function. For example, it may be an oscillator, a transducer, a signal filter, an operational amplifier, or any other analog electronic function suitable to those skilled in the art.The functional electronic circuit can incorporate any electronic component that enables the implementation of the electronic function. For example, the functional electronic circuit can incorporate a resistor, a capacitor, an inductor, a diode, a transistor, a regulator, a switch, a potentiometer, a microprocessor, a microcontroller, computer memory, a microphone, a loudspeaker, a photodiode, a temperature sensor, or any other electronic component suitable to a person skilled in the art.

[0031] The at least two electronic boxes 2 are configured to interconnect so as to form an overall functional electronic circuit by electrical connection of the functional electronic circuits of said at least two electronic boxes.

[0032] According to one embodiment, for each electronic unit 2, the functional electronic circuit may include a functional input connector 3 configured to connect to a functional output connector 4 of a possible upstream electronic unit 2. The functional input connector 3 thus allows receiving a functional input signal from the functional output connector 4 of the possible upstream electronic unit 2.

[0033] As in the exemplary embodiment shown in Figure [Fig. 1], the input functional connector 3 can be configured to connect directly to the output functional connector 4. The input functional connector 3 may include one or more input functional contacts 31, 32. In a preferred embodiment shown in Figures [Fig. 1], [Fig. 3], and [Fig. 4], the input functional connector 3 includes two input functional contacts 31, 32. The input functional contactor(s) 31, 32 may have the form of a cylindrical metal rod as shown in Figures [Fig. 1], [Fig. 3], and [Fig. 4]. The cylindrical metal rod may be retractable and spring-mounted so as to exert a The force exerted by the spring ensures that the metal rod is extended. This type of contactor is generally referred to as a "pogo pin." Thanks to the force exerted by the spring, it maintains electrical contact between connected input and output contactors, for example, between an input functional contactor 31 and an output functional contactor 41. In alternative embodiments, the input functional contactor(s) 31, 32 may have a metal blade shape, a cylindrical housing, a rod shape, a conical housing, or any other shape suitable to those skilled in the art. The input functional contactor(s) 31, 32 may be made of copper, gold, aluminum, or any other electrically conductive material suitable to those skilled in the art.

[0034] In one embodiment, the input functional connector 3 can be configured to connect to the output functional connector 4 via an electronic link 10. This link may, for example, be in the form of an electrical cable. As in the previous embodiment, the input functional connector 3 may include one or more input functional contactors 31, 32 similar to those previously described. The electrical cable may also include one or more contactors. These contactors preferably have a shape suitable for creating electrical contact with the input functional contactor(s) 31, 32. In particular, the contactor(s) of the electrical cable may have a shape complementary to that of the input functional contactor(s) 31, 32.The electrical cable contactor(s) may, for example, have a cylindrical metal housing suitable for receiving the functional input contactor(s) 31, 32 in the form of a cylindrical metal rod. In alternative embodiments, the electrical cable contactor(s) may have a metal blade shape, a cylindrical rod shape, a conical rod or housing shape, or any other shape suitable to those skilled in the art.

[0035] The functional electronic circuit may also include a functional output connector 4 configured to connect to a functional input connector 3 of a possible downstream electronic unit 2. The functional output connector 4 thus allows the transmission of a functional output signal towards the functional input connector 3 of the possible downstream electronic unit 2.

[0036] As in the embodiment shown in Figure [Fig. 2], the output functional connector 4 can be configured to connect directly to the input functional connector 3. The output functional connector 4 can include one or more output functional contacts 41, 42. In a preferred embodiment shown in Figures [Fig. 2] and [Fig. 5], the output functional connector 4 includes two output functional contacts 41, 42. The output functional contactor(s) 41, 42 preferably have a shape suitable for creating a contact electrical connection with the input functional contactor(s) 31, 32. In particular, the output functional contactor(s) 41, 42 may have a shape complementary to the input functional contactor(s) 31, 32. As shown in Figures [Fig. 2] and [Fig. 5], the output functional contactor(s) 41, 42 may, for example, have a cylindrical metal housing suitable for receiving the input functional contactor(s) 31, 32, which may be cylindrical metal rods. In alternative embodiments, the output functional contactor(s) 41, 42 may have a metal blade, cylindrical rod, conical rod or housing shape, or any other shape suitable to those skilled in the art. The output functional contactor(s) may be made of copper, gold, aluminum, or any other electrically conductive material suitable to those skilled in the art.

[0037] In one embodiment, the output functional connector 4 can be configured to connect to the input functional connector 3 via an electronic link 10. This link can, for example, be in the form of an electrical cable. As in the previous example, the output functional connector 4 can include one or more output functional contactors 41, 42 similar to those previously described. In particular, the output functional connector 4 can have a shape similar to the input functional connector 3. The electrical cable can then include one or more contactors. These contactors preferably have a shape suitable for creating electrical contact with the output functional contactor(s) 41, 42. In particular, the contactor(s) of the electrical cable can have a shape complementary to the output functional contactor(s) 41, 42.The electrical cable contactor(s) may, for example, have a cylindrical metallic housing suitable for receiving one or more functional output contactors 41, 42 in the form of a cylindrical metallic rod. In alternative embodiments, the electrical cable contactor(s) may have a metallic blade shape, a cylindrical rod shape, a rod or conical housing shape, or any other shape suitable to those skilled in the art.

[0038] With reference to Figures [Fig. 3] and [Fig. 5], one or more electronic housings 2 may include a secondary output functional connector 4'. This connector is configured to connect to an input functional connector 3, or to a secondary output functional connector 4', of a possible second downstream electronic housing 2. The secondary output functional connector 4' thus allows the output functional signal to be transmitted to said input functional connector 3, or to the secondary output functional connector 4', of the possible second downstream electronic housing 2. The secondary output functional connector 4' is of a similar design to the output functional connector 4. As with the output functional connector 4, the secondary output functional connector 4' can be configured to connect directly to the input functional connector 3, respectively secondary output functional connector 4, or alternatively, via an electronic link 10 of the same type as previously described.

[0039] Referring to Figure [Fig. 4], one or more electronic units 2 may include a secondary input functional connector 3'. This connector is configured to connect to an output functional connector 4 of a possible second upstream electronic unit 2. The secondary input functional connector 3' thus allows the reception of an input functional signal from the output functional connector 4 of the possible second upstream electronic unit 2. The secondary input functional connector 3' is of a similar design to the input functional connector 3. As with the input functional connector 3, the secondary input functional connector 3' can be configured to connect directly to the output functional connector 4, or alternatively, via an electronic link 10 of the same type as previously described.

[0040] The design tool 1 also includes a control unit. The control unit may include a microprocessor and memory in which one or more computer programs are stored. The control unit may also include an interface. The latter may include a screen, which may or may not be touch-sensitive, a keyboard, a mouse, or any interface device suitable to a person skilled in the art.

[0041] The control unit is configured to generate a digital model of the overall functional electronic circuit. In practice, the execution of a computer program stored in memory, when run by the microprocessor, enables the implementation of the digital modeling of the overall functional electronic circuit. "Generating a digital model of the overall functional electronic circuit" means modeling one or more physical effects of the overall functional electronic circuit. These physical effects may, for example, be electrical, electromagnetic, luminous, thermal, logical, or any other physical effect understood by those skilled in the art. The modeling may, in particular, be based on a transfer function of the overall functional electronic circuit and / or on a transfer function of the functional electronic circuit of one or more electronic modules 2.Modeling may also include a graphical representation step. In particular, the control unit can be configured to display a graphical representation of the overall functional electronic circuit on a screen. This graphical representation may be in the form of a... electrical diagram, a grarcet or any other graphical representation suitable to a person skilled in the art.

[0042] According to one embodiment, the control unit can be configured to identify the functional electronic circuit of each of the at least two interconnected electronic enclosures 2. "Identifying the functional electronic circuit" means acquiring all information relating to the functional electronic circuit necessary for digital modeling. For example, each electronic enclosure 2 may have a unique identifier. By reading this identifier, the control unit can identify the functional electronic circuit of the electronic enclosure 2.

[0043] For example, referring to Figure [Fig.6], when the control unit reads the identifier "IdOl" from the first electronic box 2, the control unit identifies the functional electronic circuit as an analog electronic function of the voltage generator type.

[0044] Similarly, by reading the identifiers "Id02" and "Id04", the control unit identifies the functional electronic circuit of each of the associated electronic boxes 2 as an analog electronic function of the variable resistor type.

[0045] Also, by reading the identifiers "Id03", "Id05", "Id06", "Id08", "Idl0", and "Idl2", the control unit identifies the functional electronic circuit of each of the associated electronic units 2 as an analog electronic function of the electrical node type. This functional electronic circuit is configured to electrically connect the input functional connector 3 with the output functional connectors 4, 4'. "Electrically connect" means that the same electrical voltage is applied to the input functional connector 3 and to the output functional connectors 4, 4'. The voltage transfer function associated with this analog electronic function is therefore equal to 1. For example, the electronic unit 2 with the identifier "Id03" allows the following three functional connectors to be electrically connected: • the functional output connector 4, of the electronic box 2 bearing the identifier “Id02”, connected to the electrical input connector 3 of said electronic box bearing the identifier “Id03”, • the electrical input connector 3, of the electronic box 2 bearing the identifier “Id04”, connected to the electrical output connector 4 of said electronic box bearing the identifier “Id03”, • the secondary output electrical connector, of the electronic box 2 bearing the identifier “Id06”, via an electrical cable 10 connected to the secondary output electrical connector 4' of said electronic box bearing the identifier "Id03".

[0046] Also, by reading the identifiers "Id07" and "Idl3", the control unit identifies the functional electronic circuit of each of the associated electronic boxes 2 as an analog electronic function of the variable capacitance capacitor type.

[0047] Also, by reading the identifier "Id09", the control unit identifies the functional electronic circuit, of the associated electronic box 2, as being an analog electronic function of the operational amplifier type.

[0048] Also, by reading the identifier "Idl 1", the control unit identifies the functional electronic circuit, of the associated electronic box 2, as being an analog electronic function of the voltmeter type.

[0049] Also, by reading the identifier "Idl4", the control unit identifies the functional electronic circuit, of the associated electronic box 2, as being an analog electronic function of ground type.

[0050] According to another embodiment shown in Figure [Fig. 7], when the control unit reads the identifier "Id51", "Id52", or "Id53" from the first row of electronic modules 2, the control unit identifies the functional electronic circuit as a digital electronic function of the "true or false" logic gate type. In practice, a switch allows the value to be changed from "true" to "false". The switch can be manually operated, as shown in Figures [Fig. 1] and [Fig. 2], and / or electrically operated.

[0051] Similarly, upon reading the identifier “Id54”, the control unit identifies the functional electronic circuit of the associated electronic box 2 as a digital electronic function of the “and” logic gate type.

[0052] Similarly, upon reading the identifier “Id55”, the control unit identifies the functional electronic circuit, of the associated electronic box 2, as a digital electronic function of the “not” logic gate type.

[0053] Similarly, upon reading the identifier “Id56”, the control unit identifies the functional electronic circuit of the associated electronic box 2 as a digital electronic function of the “or” logic gate type.

[0054] Similarly, upon reading the identifier "Id56", the control unit identifies the functional electronic circuit, of the associated electronic box 2, as a digital electronic function of the state light-emitting diode type.

[0055] In one embodiment, the control unit can identify the functional electronic circuit of each of the at least two interconnected electronic housings 2 by means of image recognition. To do this, the control unit can be equipped with one or more configured digital cameras to capture one or more images of the assembly of at least two interconnected electronic boxes 2. The control unit can then determine, from the image(s), which functional circuit equips each of the at least two electronic boxes 2.

[0056] In addition, the control unit can be configured to identify the interconnection or interconnections between the at least two electronic boxes 2. “Identifying the interconnection or interconnections between the at least two electronic boxes” means acquiring all information relating to the interconnections of the electronic boxes 2, in particular the interconnections of the functional electronic circuits, necessary for numerical modeling.

[0057] In practice, the control unit can be configured to identify that the electrical input connector 3 of a first electronic enclosure 2 is connected to the electrical output connector 4 of a second electronic enclosure 2. Alternatively, the control unit can be configured to identify that the electrical input connector 3 of the first electronic enclosure 2 is disconnected. Similarly, the control unit can be configured to identify that the electrical output connector 4 of the electronic enclosure 2 is connected to the electrical input connector 3 of a third electronic enclosure 2. Alternatively, the control unit can be configured to identify that the electrical output connector 4 of the first electronic enclosure 2 is disconnected.When the first electronic box 2 has a secondary input connector 3', the control unit can be configured to identify that said secondary input electrical connector is either disconnected or connected to the output electrical connector 4 of a fourth electronic box 2. When the first electronic box 2 has a secondary output connector 4', the control unit can be configured to identify that the secondary output electrical connector is either disconnected or connected to the input electrical connector 3 of a fifth electronic box 2, or connected to the secondary output electrical connector 4' of the fifth electronic box 2.

[0058] For example, with reference to Figure [Fig.6], the control unit can be configured to identify that: • The functional input connector 3 of the electronic box 2, bearing the identifier "IdOl", is disconnected. • The functional input connector 3 of the electronic box 2, bearing the identifier "Id02", is connected to the functional output connector 4 of the electronic box 2, bearing the identifier "IdOl", • The functional input connector 3 of the electronic box 2, bearing the identifier "Id03", is connected to the functional output connector 4 of the electronic box 2, bearing the identifier "Id02", • The functional input connector 3 of the electronic box 2, bearing the identifier "Id04", is connected to the functional output connector 4 of the electronic box 2, bearing the identifier "Id03", • The secondary output functional connector 4' of the electronic box 2 bearing the identifier "Id06" is connected to the secondary output functional connector 4' of the electronic box 2 bearing the identifier "Id03", • and so on.

[0059] A similar identification could be made for the example embodiment shown schematically in figure [Fig.7].

[0060] According to one embodiment, a unique set of coordinates associated with each electronic unit 2 can allow the identification of the interconnection(s) between the at least two electronic units 2. The coordinate system can be a two-dimensional (X; Y) relative coordinate system. A "relative coordinate system" is understood to mean that the coordinate set of a first electronic unit 2 expresses its relative position with respect to a second electronic unit 2. For example, for a first electronic unit 2 having a first set of coordinates (XI; YI): • a second electronic box 2 connected to the functional input connector 3 of said first electronic box may include a second set of coordinates (XI-1; Yl), • a third electronic box 2 connected to the functional output connector 4 of said first electronic box may include a third set of coordinates (Xl+1 ; Yl), • a fourth electronic box 2 connected to the secondary output functional connector 4' of said first electronic box may include a third set of coordinates (Xl+1 ; Yl+1), • a fourth electronic box 2 connected to the secondary input functional connector 3' of said first electronic box may include a third set of coordinates (Xl-1 ; Yl+1).

[0061] Thus, by reading the coordinate sets, the control unit can identify the interconnection(s) between the at least two electronic boxes 2.

[0062] In alternative embodiments, the coordinate system may be a three-dimensional relative coordinate system (X; Y; Z) or any other coordinate system suitable to a person skilled in the art.

[0063] For example, referring to figure [Fig.6], and with a coordinate system: • the electronic box 2 bearing the identifier “IdOl” may contain the set of coordinates (0 ; 0), • the electronic box 2 bearing the identifier “Id02” may contain the coordinate set (1 ; 0), • the electronic box 2 bearing the identifier “Id03” may contain the coordinate set (3 ; 0), • the electronic box 2 bearing the identifier “Id04” may contain the coordinate set (4 ; 0), • the electronic box 2 bearing the identifier “Id06” may contain the coordinate set (4; 1), • and so on.

[0064] Thus, the control unit can identify that the input functional connector 3 of the electronic box 2 having the coordinate set (1; 0) is connected to the output functional connector 4 of the electronic box 2 having the coordinate set (0; 0), and so on.

[0065] A similar line of reasoning can be applied to the example of realization of the figure [Fig.7].

[0066] In one embodiment, the control unit can identify the interconnection(s) between the at least two electronic housings 2 by means of image recognition. To do this, the control unit can be equipped with one or more digital cameras configured to capture one or more images of the assembly of the at least two interconnected electronic housings 2. The control unit can then determine, from the image(s), the interconnection(s) between the at least two electronic housings.

[0067] In one embodiment, the control unit can identify the interconnection(s) between the at least two electronic boxes based on the transition times of the control signal between the control unit and each of the at least two electronic boxes 2. In this embodiment, the control unit is preferably configured to communicate directly with each of the at least two electronic boxes 2. To do this, the control unit can communicate directly with the electronic boxes 2 by means of a wired data bus link, for example a CAN (Controller Area Network) data bus, or a wireless link, for example wifi or Bluetooth, or by any other means of communication suitable to a person skilled in the art.

[0068] The control unit can then be configured to generate a digital model of the overall functional electronic circuit from the identification of the functional electronic circuits and the identification of the interconnection(s).

[0069] In one embodiment, the control unit can, for each of the identified functional electronic circuits, select from a database a transfer function associated with said identified functional electronic circuit. The unit The command can then determine, based on the selected transfer functions and the identified interconnection(s), an overall transfer function of the overall functional electronic circuit.

[0070] In one embodiment, each electronic unit may include an electronic control circuit configured to send and / or receive a control signal. The electronic control circuit may include a microprocessor and memory in which a computer program may be stored. In practice, the microprocessor's execution of the computer program stored in memory may enable the sending or receiving of the control signal through a communication interface. The communication interface may be in the form of control connectors capable of interconnecting. The electronic control circuit may, in particular, include an input control connector 5 configured to connect to an output control connector 6 of a possible upstream electronic unit 2.The input control connector 5 thus allows receiving an input control signal from the output control connector 6 of the possible upstream electronic box 2.

[0071] As in the exemplary embodiment shown in Figure [Fig. 1], the input control connector 5 can be configured to connect directly to the output control connector 6. The input control connector 5 may include one or more input control contactors 51, 52. In a preferred embodiment shown in Figures [Fig. 1], [Fig. 3], and [Fig. 4], the input control connector 5 includes two input control contactors 51, 52. The input control contactor(s) 51, 52 may have shapes similar to those of the input functional contactors 31, 32. The input control contactor(s) 51, 52 may be made of materials similar to those of the input functional contactors 31, 32.Similar to the input functional connector 3, the input control connector 5 can, in certain embodiments, be configured to connect to the output control connector 6 via an electronic link 10. The latter is similar to the electronic link 10 previously described.

[0072] The electronic control circuit may also include an output control connector 6 configured to connect to an input control connector 5 of a possible downstream electronic unit 2. The output control connector 6 thus allows the transmission of an output control signal towards the functional input connector 5 of the possible downstream electronic unit 2.

[0073] As in the embodiment shown in Figure [Fig. 2], the output control connector 6 can be configured to connect directly to the input control connector 5. The output control connector 6 can comprising one or more output control contactors 61, 62. In a preferred embodiment shown in Figures [Fig. 2] and [Fig. 5], the output control connector 6 comprises two output control contactors 61, 62. The output control contactor(s) 61, 62 preferably have a shape suitable for creating electrical contact with the input control contactor(s) 51, 52. In particular, the output control contactor(s) 61, 62 may have a shape complementary to the input control contactor(s) 51, 52. The output control contactor(s) 61, 62 may have shapes similar to those of the output functional contactors 51, 52. The output control contactor(s) 61, 62 may be made of materials similar to those of the output functional contactors 51, 52.Similar to the output functional connector 4, the output control connector 6 can, in certain embodiments, be configured to connect to the input control connector 5 via an electronic link 10. The latter is similar to the electronic link 10 previously described.

[0074] Similarly, the electronic control circuit may also include a secondary input control connector 5' as shown in Figure [Fig.4] and / or a secondary output control connector 6' as shown in Figures [Fig.3] and [Fig.5].

[0075] Thus, via the control connectors 5, 5', 6, 6', a first electronic unit 2 can be configured to communicate with the electronic units 2 to which it is connected. In particular, a first electronic unit 2 can send a control signal to a second electronic unit 2 whose input control connector 5 is connected to the output control connector 6 of said first electronic unit. The control signal may, in particular, include a data set incorporating the coordinate set (XI; Yl) ​​of the first electronic unit 2. Upon receiving the control signal, the electronic control circuit of the second electronic unit 2 can then determine its own coordinate set (Xl+1; Yl).Thus, once a set of coordinates is associated with one of the electronic boxes 2, each of the other electronic boxes 2 can determine its own set of coordinates by propagation of the control signal between the connected electronic boxes 2.

[0076] The control signal may include a data file in which various data can be encapsulated. In particular, for each electronic unit 2, the electronic control circuit may encapsulate in the data file its identifier and the set of coordinates of said electronic unit.

[0077] The control unit can then be configured to send the control signal to an electronic box 2 and / or respectively receive the signal from Command originating from an electronic control unit 2. As described previously, the control unit may include a microprocessor and memory in which a computer program can be stored. In practice, the microprocessor's execution of the computer program stored in memory allows the sending or receiving of the control signal through a communication interface.

[0078] In a preferred embodiment, the control unit can be configured to communicate with only one of the electronic boxes 2. This electronic box 2 is then referred to as the "master electronic box".

[0079] For example, with reference to Figure [Fig. 6], the electronic box bearing the identifier "IdOl" can be configured to function as the master electronic box. In alternative embodiments, another of the electronic boxes 2 can be configured to function as the master electronic box.

[0080] With reference to Figure [Fig. 7], the electronic unit bearing the identifier "Id51" can be configured to function as the master electronic unit. In alternative embodiments, another of the electronic units 2 can be configured to function as the master electronic unit.

[0081] The master electronic control unit 2 can be connected to the control unit via a wired or wireless communication interface. Preferably, the master electronic control unit 2 is connected to the control unit via a wired USB communication interface. In alternative embodiments, the master electronic control unit 2 is connected to the control unit via a Wi-Fi, Bluetooth, or any other wired or wireless communication interface suitable to those skilled in the art.

[0082] When the identification of the interconnection(s) between the at least two electronic units 2 is performed using a single coordinate set as previously described, the control unit can be configured to assign a source coordinate set to the master electronic unit 2. For example, for a two-dimensional coordinate set, the control unit can be configured to assign the coordinate set (0, 0) to the master electronic unit 2. In practice, the control unit can be configured to send a control signal to the master electronic unit 2. This control signal can include a data set in which the coordinate set (0, 0) is assigned to the master electronic unit 2. The electronic control circuit of the master electronic unit 2 can then encapsulate its identifier associated with the coordinate set (0, 0) in the data file.The master electronic box 2 can then be configured to send the control signal to a downstream electronic box 2 whose connector. The input control connector 5 is connected to the output control connector 6 of the master electronic control unit. The downstream electronic control unit 2 can then be configured to determine its own coordinate set (1; 0), to encapsulate its identifier and coordinate set within the control signal data set, and to transmit this control signal to the next electronic control unit 2. Once all the electronic control units 2 have encapsulated their identifiers and coordinate sets, the control signal can be returned to the control unit via the master electronic control unit 2. The control unit then has all the necessary information to: • to identify the functional electronic circuit of each of the at least two interconnected electronic enclosures, and • to identify the interconnection(s) between at least two electronic boxes 2.

[0083] From the identification of the functional electronic circuits and the identification of the interconnection(s), the control unit can then generate a digital model of the overall functional electronic circuit as previously described.

[0084] In one embodiment, the control unit may comprise, on the one hand, a computing unit configured to generate a digital model of the overall functional electronic circuit and, on the other hand, a specific master electronic unit capable of communicating with the electronic units 2. The master electronic unit may then be connected to the computing unit via a wired or wireless communication interface, for example, USB. The computing unit may, in particular, be in the form of a computer. The master electronic unit differs from the electronic units 2 in that it lacks a functional electronic circuit. The master electronic unit does, however, include a control electronic circuit. This control circuit is of the same type as the control electronic circuit of the electronic units 2 described above.Similar to the electronic control units 2, the master electronic control unit's electronic control circuit may include an input control connector 5 and an output control connector 6 so as to allow interconnection with a downstream electronic control unit 2 and / or an upstream electronic control unit 2. The operation of the master electronic control unit of the control unit is similar to the operation previously described for the master electronic control unit 2.

[0085] In one embodiment, the control unit can be configured to communicate with several electronic boxes 2. In another embodiment, the control unit can be configured to communicate with all electronic boxes 2.

[0086] According to one embodiment, one or more electronic housings 2 may include a control element. This control element is configured to modify the value of an electronic characteristic of the functional electronic circuit of the electronic housing 2. The control unit can then be configured to control said control element so as to modify the value of said electronic characteristic so that said value is equal to a predetermined value. The value of said electronic characteristic can be selected, or entered, via a computer interface of the control unit. In practice, the execution by the microprocessor of the control unit of a computer program stored in a memory of the control unit makes it possible to: • select, or enter, via a computer interface of the control unit, the desired value of the electronic characteristic, • control the adjustment device of the electronic box 2 so as to modify the value of the electronic characteristic so that it corresponds to the desired value.

[0087] For example, with reference to Figure [Fig. 6], the electronic unit 2, identified as "Id02", comprises a functional electronic circuit incorporating an analog electronic function of the variable resistor type. In one embodiment, the functional electronic circuit may include several resistors, each with a different value, and a microcontroller configured to select one or another of the resistors. The electrical current of the input functional signal then flows through the selected resistor. The control unit can then be configured to command the microcontroller to select the resistor associated with a desired resistance value. The desired resistance value can, for example, be selected via a computer interface of the control unit. In another embodiment, the functional electronic circuit may include a potentiometer.A similar operation can be applied to the electronic unit 2 bearing the identifier "Id04".

In one embodiment, the functional electronic circuit may include several capacitors, each with a different capacitance value, and a microcontroller configured to select one or another of the capacitors. The electrical current of the input functional signal then flows through the selected capacitor. The control unit can then be configured to command the microcontroller to select the capacitor associated with a desired capacitance value. The desired capacitance value can, for example, be selected via a computer interface of the control unit. A similar operation can be applied to the electronic box 2 bearing the identifier "Id07".

[0089] Referring to Figure [Fig. 7], the electronic housing 2, identified as "Id51", comprises a functional electronic circuit incorporating a digital electronic function of the "true or false" logic gate type. In one embodiment, the functional electronic circuit may include an electrically controlled switch for toggling between the "true" and "false" values. The control unit can then be configured to control the switch so as to select the desired "true" or "false" value. The desired "true" or "false" value can, for example, be selected via a computer interface of the control unit.

[0090] In one embodiment, the adjustment element of an electronic control unit 2 can also be manually controlled on the electronic control unit 2. For this purpose, the electronic control unit 2 may include a button, a position selector switch, or any other manual control element suitable for a person skilled in the art. The control circuit of the electronic control unit 2 can then be configured to: • determine the manually selected value of the variable electronic characteristic of the functional electronic circuit of said electronic enclosure, • send a control signal to the control unit including the identifier of said electronic box and said manually selected value.

[0091] The control unit can then be configured to modify the digital model of the overall functional electronic circuit according to the manually selected value.

[0092] According to one embodiment, one or more electronic units 2 incorporate an analog-to-digital converter. The latter can be configured to perform one or more voltage and / or current measurements on the input functional signal and / or on the output functional signal. The analog-to-digital converter can, in particular, be used as an oscilloscope. The control unit can then be configured to display a graphical representation of the measurement(s) on a screen. In practice, the control circuit of the electronic unit 2 incorporating the analog-to-digital converter is configured to send a control signal to the control unit, including a data set relating to the measurement(s). As previously described, the control signal can pass through the master electronic unit when such a unit exists.

[0093] According to one embodiment, each electronic housing may include an electronic power supply circuit configured to supply electricity to the circuit Control electronics. The power supply circuit can also be configured to supply power to the functional electronic circuit. The power supply circuit may include an input power connector 7 configured to connect to an output power connector 8 of an optional upstream electronic enclosure 2. The input power connector 7 thus receives an input power supply current from the output power connector 8 of the optional upstream electronic enclosure 2.

[0094] As in the exemplary embodiment shown in Figures [Fig. 1], [Fig. 3], and [Fig. 4], the input power connector 7 can be configured to connect directly to the output power connector 8. The input power connector 7 may include one or more input power contactors 71, 72.

[0095] As shown in Figures [Fig. 2] and [Fig. 5], the electronic power supply circuit may also include an output power connector 8 configured to connect to an input power connector 7 of a possible downstream electronic unit 2. The output power connector 8 thus allows the transmission of an output power supply current towards the functional input connector 7 of the possible downstream electronic unit 2.

[0096] As in the embodiment shown in Figure [Fig. 2], the output power connector 8 can be configured to connect directly to the input power connector 7.

The output power contactor(s) 81, 82 preferably have a shape suitable for creating electrical contact with the input power contactor(s) 71, 72. In particular, the output power contactor(s) 81, 82 may have a shape complementary to the input power contactor(s) 71, 72. The output power contactor(s) 81, 82 may have shapes similar to those of the output functional contactors 41, 42. The output power contactor(s) 81, 82 may be made of materials similar to those of the output functional contactors 41, 42. Similar to the output functional connector 4, the output power connector 8 may, in certain embodiments, be configured to connect to the input power connector 7 via an electronic link 10. The latter is similar to the electronic link 10 previously described.

[0097] Similarly, the electronic power supply circuit may also include a secondary input power connector 7' as shown in Figure [Fig.4] and / or a secondary output power connector 8' as shown in Figures [Fig.3] and [Fig.5].

[0101] Similarly, and as shown in Figures [Fig.2] and [Fig.5], the output functional connector 4, the output control connector 6 and the output power connector 8 can be arranged on a rear face 13 of the electronic housing 2.

[0102] Magnets 11 can be arranged on the front face 12 and the rear face 13 of the electronic housing 2.
