Background Art

[0002] 2. Description of Related Art Electrical components such as metal-oxide-semiconductor field-effect transistors (MOSFETs) have multiple terminals (pins) to which voltage can be applied, such as the gate, body, source, and drain. Typically, the voltage between the gate and source terminals determines the conductivity between the source and drain terminals. Various parameters (operating conditions) affect the behavior of a MOSFET, and traditionally, data is collected (compiled) by measuring one or more MOSFETs in a physical circuit to collect data on the various operating conditions the MOSFETs experience. A datasheet can then be prepared to present a summary of the measurement data for one or more MOSFETs, and by using the data measured from one or more MOSFETs to create a model, such as a SPICE model, the behavior of the MOSFETs under other operating conditions can be predicted. Before assembling a circuit, the behavior of the MOSFETs in the circuit can be simulated using the model to predict how they will function in the circuit. This datasheet is often sent to users considering ordering MOSFETs as a PDF file or provided to the user along with the MOSFETs, and the user can use this data to build a circuit that includes the MOSFETs.

[0003] Figure 1 shows an example of a datasheet. Electronic components have various parameters. These are listed in the "Parameter" column, with the corresponding symbol in the "Symbol" column. The "Unit" column specifies the unit used to measure the corresponding parameter. Each parameter is associated with one or more operating conditions listed in the "Condition" column. These are the operating conditions for the electronic component. The "min," "typ," and "max" columns show the minimum, typical, and maximum values ​​of the parameter under the operating conditions, respectively. For example, if the operating conditions are in the range of 25°C to 175°C, the voltage V applied between the drain and source pins of the MOSFET is... DSThe voltage must be no more than 100 volts. Therefore, the "conditions" are not only operating conditions but also, in a sense, logical conditions, that is, conditions that must be true for the data in the "min", "typ", and "max" columns to be reliable. The values ​​of each "parameter" under the corresponding operating conditions can be calculated by simulating the MOSFET under various conditions, for example, using the MOSFET SPICE model. For example, as shown in Figure 1, the mounting base temperature (T mb Assuming ) = 25℃, the total power dissipation (P tot The maximum value is calculated to be 341W.

[0004] Typically, datasheet values ​​are a discrete subset of an infinite number of possible operating conditions ("driving conditions"). Therefore, if a user wants to know the parameter values ​​for operating conditions not included in the sheet, they must manually calculate the parameters or parameter P tot You need to estimate the parameters from one of the attached graphs in the row (for example, the one linked as "Figure 1").

[0005] Another problem with datasheets is that they assume a certain level of understanding of electronic component parameters, making them difficult for less experienced users to use. For example, the definition of parameters (or multiple parameters) or the relationships between them may be unclear. Looking at the datasheet in Figure 1, the parameter R DSon The term "drain-source on-resistance" is not understood by all users. Different datasheet authors may use different abbreviations or names to represent parameters. Furthermore, it can take users time to identify the corresponding pins on the physical electrical component, and without sufficient time, users may misunderstand the component's characteristics. [Overview of the Initiative] [Means for solving the problem]

[0006] This disclosure provides a computer implementation method for interactively displaying information about electrical components, an information processing device for performing the method, and a computer-readable storage medium including instructions for instructing the information processing device to perform the method.

[0007] Generally speaking, the first aspect of this disclosure proposes a graphical user interface with which a user can interact to modify one or more operating conditions in a datasheet, and after the modification of the operating conditions, the corresponding parameter values ​​for the modified operating conditions are displayed. This allows the user to obtain parameter values ​​without having to perform additional calculations or view graphs.

[0008] A second aspect of this disclosure proposes that in a graphical user interface, technical information is associated with parameters of electrical components, and when a user points to a parameter on the graphical user interface, the technical information is displayed. This may include a description of the meaning of the parameter and / or the effects it is affected by operating conditions.

[0009] A third aspect of this disclosure proposes a graphical user interface in which the pins of an electrical component are associated with the pins on the corresponding representation of the electrical component. When a user selects one of the pins on the representation of the electrical component on the graphical user interface, the same associated pins on other representations are also identified (graphically highlighted).

[0010] Any one or more of the above aspects of this disclosure can be freely combined in a single graphical user interface, thereby providing a product for understanding the operation and usage conditions of electronic components. The graphical user interface may be provided to a user in the form of a computer program product, which includes, for example, program instructions that operate to generate the graphical user interface when implemented by the processor of a computer system, and a database of technical information used by the program instructions. The user may be a user considering ordering electrical components or a user designing an electronic circuit. Alternatively, the computer program product may be provided to a user who already owns electrical components (for example, provided together with the electrical components), and the user can use the information obtained from the graphical user interface to construct a circuit including the electrical components.

[0011] Accordingly, the present disclosure provides a method for designing and / or constructing an electronic circuit, the method comprising: obtaining information about electronic components using a graphical user interface as described above; forming a design of an electronic circuit including the electronic components based on that information (for example, selecting one or more other electronic components of the electronic circuit, and / or the locations of the electronic components of the electronic circuit, and / or the locations of the conductive paths of the electronic circuit based on that information); and optionally, physically constructing the electronic circuit based on the design.

[0021] [Figure 7] This is a flowchart of a third method, which is one embodiment of the present disclosure. [Modes for carrying out the invention]

[0022] Hereinafter, an embodiment of the present disclosure, a computer implementation method for interactive display of the electrical properties of an electrical component, will be described with reference to Figures 2A and 2B. “Electrical component” means at least one electronic element having a plurality of conductive terminals ("pins") for transmitting electrical signals to and from the component. Suitable examples of electronic components include any of the following: bipolar transistors, diodes, ESD (electrostatic discharge) protection elements, transient voltage suppressors, signal modulating elements, MOSFETs (metal oxide semiconductor field-effect transistors), GaN FETs (gallium nitride field-effect transistors), analog and logic ICs (integrated circuits), and IGBTs (insulated-gate bipolar transistors). The term “electronic component” also includes components defined by function, such as amplifiers, comparators, attenuators, controllers, drivers, interfaces, switches, memory, microcontrollers, processors, multimedia, power management, and lighting elements. An "electronic component" is typically an integrated electronic element, but in some cases, it may be a set of integrated units configured to work together to form an electronic component, such as a power module or a motor drive unit. The above-mentioned electronic components are components with variable parameters, but some electronic components with pins do not have variable parameters, such as light bulbs, plugs, and connectors.

[0023] This embodiment is a graphical user interface (GUI) presented to a user by a computer system operated by the user. The computer system includes a processor, a display device controlled by the processor, and one or more data input devices such as a pointer device (such as a computer mouse) or a touch-sensitive screen. The GUI may be generated, for example, by a computer program product provided to the computer system as an application (for example, downloaded via a communication system such as the Internet). This product may be provided by a manufacturer of electrical components. Optionally, this product may be provided together with the electrical component(s), for example, on a tangible recording medium provided with the component. Alternatively, it may be downloaded separately, for example, by a user considering ordering, or who has ordered or obtained, one of the electrical components.

[0024] The initial appearance of the display generated by the GUI may be similar to the fixed datasheet shown in Figure 1, especially if the electrical component is a MOSFET, but in the modifications of this embodiment, the GUI may provide information on other electronic components. As described above, electronic components have various parameters, which may be listed in the “Parameters” column, with the corresponding symbol in the “Symbol” column. The “Units” column specifies the units used to measure the corresponding parameter. Each parameter is associated with one or more other parameters listed in the “Conditions” column. These are the operating conditions of the electronic component. The “min,” “typ,” and “max” columns show the minimum, typical, and maximum values ​​of the parameter under the operating conditions, respectively. In the following description, “Conditions” will be referred to as “First Parameters,” and “Second Parameters” (those listed in the “Parameters” column) depend on them. The first parameters may be thought of as input parameter values ​​for the electronic component, and the second parameters may be thought of as the resulting output parameter values. For example, the second parameter “Drain Current” Dis shown as being dependent on two first parameters, the voltage V between the gate and the source, in a display similar to FIG. 1 generated by the GUI. GS and the mount base temperature T mb and can be shown as depending on two first parameters.

[0025] In contrast to the above-described known data sheet, the user can select one field of the first parameters that specify the corresponding conditions using the data input device of the computer system. When a field is selected, at least one data input element regarding one or more of the first conditions is displayed. For example, FIG. 2A shows a display generated by the GUI which is an embodiment of the present disclosure when the user selects the box of the parameters (conditions) of the row corresponding to the drain current (I D ). In this case, the data input elements are slider bars 21 and 22. The initial value of V GS is 10 V, and the initial temperature T mb of the device is 61 °C. The corresponding initial maximum values of the second parameter P tot and I D are 259 W and 232 A, respectively. The user has the option to modify one value of V GS or T mb , or neither, or both, using the respective slider bars 21 and 22 of the two second parameters.

[0026] As shown in FIG. 2B, the GUI receives from the user the value of at least one first parameter that characterizes the operating conditions of the electrical component. Specifically, as shown in FIG. 2B, the user selects the condition (first parameter) V GS and modifies the initial value to 7 V, and the condition (first parameter) T mbThe initial value is changed to 101°C by selecting this option. Each of these changes is made by entering the desired value using the respective slider control (for example, by operating it with a mouse, or with the user's finger if the screen is touch-sensitive). The input method is not limited; for example, it could be a field for the user to manually enter the desired value by typing.

[0027] By executing program instructions associated with the GUI, the computer system obtains a second parameter (in this example, the second parameter I) that indicates the electrical characteristics of the MOSFET when it is operated according to the operating conditions (which may be multiple) specified by the received parameter(s). D Get the value of (for example, by calculating it as described below).

[0028] In some cases, a computer system may calculate the value of at least one second parameter by simulating the MOSFETs in the circuit under their operating conditions using the modified first parameter(s) (and any unmodified first parameter(s)). Alternatively, the value of at least one second parameter may be extracted from other sources or databases, such as SPICE models. These databases may be provided with interactive datasheets or made available on the cloud.

[0029] In the example in Figure 2B, V GS and T mb As a result of the correction, the I displayed to the user D The value of is V GS and T mb It changes because it depends on both of them. Furthermore, P tot T mb Depends on the drain-source on-resistance (R DSon ) is I D Because it depends on P tot and R DSon Figure 2B shows that the value of also changes.

[0030] In the above, V GS and T mb Both are called the "first parameter," and I D This was the "second parameter" related to them. In this example, the values ​​of the two first parameters were changed, but this is not mandatory, and the user can change them if desired. GS only or T mb It is also possible to modify only one parameter. To illustrate the above steps in another way, the user inputs a change in the value of at least one first parameter via the GUI, and as a result, the corresponding value of at least one second parameter associated with the modified value of the first parameter is displayed.

[0031] The calculations performed to determine the modified values ​​for the second parameter(s) can be executed after the user has entered the modified values ​​for the first parameter(s), for example, using a MOSFET SPICE model.

[0032] Alternatively, because this can be time-consuming, the values ​​of each possible option for the first parameter(s) of the second parameter(s) may be pre-calculated and stored. The possible options for the first parameter(s) are called the "additional values" of the first parameter(s), and the corresponding values ​​of the second parameter(s) calculated using the additional values ​​of the first parameter(s) are called the "additional values" of the second parameter(s).

[0033] If a user enters at least one modification value for the first parameter that is the same as one of the additional values ​​for the first parameter via the GUI, the calculated additional value for the second parameter corresponding to the generated additional value for the first parameter may be extracted from the store and displayed.

[0034] Alternatively, if the user enters a modified value for the first parameter via the GUI that is not the same as one of the generated additional values ​​for the first parameter, the value of the second parameter is calculated to represent the electrical characteristics of the MOSFET when operated according to the operating conditions specified by the modified value of the first parameter.

[0035] The value of the second parameter, which represents the electrical characteristics of the MOSFET when operated according to the operating conditions specified by the modification value of the first parameter, can be calculated using the MOSFET SPICE model.

[0036] Alternatively, an interpolation algorithm can be used to calculate the value of the second parameter based on additional values ​​of the first and second parameters.

[0037] For example, consider the case where there is only one first parameter and only one second parameter that depends on it. The additional values ​​of the first parameter can be thought of as an ordered sequence, where for i=1, ....n, {x i This can be written as}, where the integer n is the number of additional values ​​for the first parameter. The corresponding additional values ​​for the second parameter are {y} for i=1, ....n i It can be written as}. m The value of the modification of the first parameter, which can be expressed as, is two of the additional values ​​of the first parameter (for example, x j and x j+1 (where j is an integer in the range from 1 to n-1), and for some real number a, x m =ax j +(a-1)x j+1 If so, the modified first parameter x m The second parameter y corresponds to m The value of y m =ay j +(a-1)y j+1 This is possible. In other embodiments, other more advanced interpolation methods may be used, such as interpolation methods that enable interpolation when multiple first parameters are present.

[0038] The MOSFET SPICE model and interpolation algorithm that can be used to calculate the value of the second parameter (or more) can be run locally, i.e., on the user's computer displaying the GUI, or on a server that the user's computer can communicate with via a data communication network.

[0039] Looking again at the examples in Figures 2A and 2B, we see two parameters (V GS and T mb ) has been corrected. However, unless both parameters are corrected at the same time, V GS It has been corrected, but T mb This is the period that has not been corrected, or T mb It has been corrected, but V GS This will result in a period where the correction is not applied. In such a scenario, there are two parameters (both I D (I d As soon as any of the first parameters (which are related to ) are modified, the value of the second parameter, for example I D (I d The updated value of the first parameter (in this example, V) may be displayed. The advantage of displaying the value of the second parameter corresponding to the modification as soon as the user modifies the value of the first parameter is that the user can better understand how the modification of the first parameter affects the value of the second parameter. Alternatively, the modified value of the second parameter may not be displayed until both values ​​of the first parameter in the same field have been modified, or until an action instruction is received from the user (for example, until the user clicks a button). GS and T mb The advantage of waiting until all values ​​of the second parameter are corrected or until an execution instruction is received is that it requires fewer computational resources because only the final value is shown. Furthermore, it reduces the likelihood of the user being overwhelmed by the successive display of multiple values ​​for the second parameter.

[0040] The first parameter(s) can be any parameter on which the second parameter depends. For example, in the context of a MOSFET, the first parameter(s) can be the junction temperature (T j ), gate-source voltage (V GS ), Mount base temperature (T mb ), drain current (I D ), drain-source voltage (V DS ), gate-source voltage (V GS ), power supply voltage (V sup ), gate-source resistance (R GS ), pulse duration (t p ), and source-drain current (I s ) can be any one or more of the following.

[0041] The second parameter(s) can be any parameter that changes as a result of changes in the other parameters. For example, in the context of a MOSFET, the second parameter(s) can be the drain-source voltage (V). DS ), drain current (I D ), threshold voltage, drain leakage, total power consumption (P tot ), junction temperature (T j ) 、 Drain-source on-resistance (R DSon ), gate-drain charge (Q GD ), total gate charge (Q G(tot) ), non-repetitive drain-source avalanche energy (E DS(AL)S ), recovered charge (Q r ), and drain-gate voltage (V DGR ) can be any one or more of these. Neither of these lists is exhaustive, and other conditions and parameters of the MOSFET may belong to either category.

[0042] As can be seen from the definitions of the first and second parameters, these lists are not mutually exclusive. For example, from Figure 1, we can see that the drain-source voltage is the second parameter with respect to the junction temperature, but the first parameter with respect to the gate-drain charge. In other words, if the junction temperature is modified, the drain-source voltage changes, and if the drain-source voltage is modified, the gate-drain charge changes.

[0043] As explained, users can input modifications to the value of the first parameter via the GUI and view the calculated value of the second parameter corresponding to the modified first parameter. Therefore, users can obtain values ​​for the second parameter other than those shown in the fixed datasheet without having to perform manual calculations or graph analysis. Furthermore, the calculated value of the second parameter corresponding to the modified first parameter can be displayed to the user in various ways. For example, the calculated value of the second parameter corresponding to the changed first parameter can be output as a static PDF with the relevant parameters updated, including a table like the one in Figure 1. Alternatively, the updated table can be presented on a static or dynamic web page for the user to view.

[0044] As mentioned above, the fixed datasheet in Figure 1 can be difficult to interpret. In one form, this GUI addresses this problem by associating technical information with each parameter of the MOSFET and displaying the associated technical information on the GUI when the user selects a parameter.

[0045] Technical information regarding one or more parameters within a datasheet may be added by the original creator of the datasheet or by someone else afterward. This technical information may, for example, describe the meaning of the parameter and / or the effects it has on operating conditions.

[0046] Figure 3A shows the drain-source on-resistance parameter R used by the user. DSon This shows the technical information displayed when you select this option. If the user wants to learn more about drain-source on-resistance, starting from the point where the GUI is in its initial state as shown in Figure 1, they can use the GUI to, for example, move a pointing device and select "R DSon You can select or highlight a parameter by selecting where the word "(RDSon)" is displayed, or by performing a "right-click" operation when your pointing device is pointing to that location on the line. DSon After a parameter is selected or highlighted, the technical information associated with that parameter is displayed in the GUI for the user to view, as shown in Figure 3A. In this example, the technical information includes both graphical and textual information, but alternatively, the technical information may include only graphical information or only textual information.

[0047] Figure 3B shows the gate-drain charge parameter Q. GD (Q gd Technical information related to ) exists, and the user can Q in the GUI GD (Q gd Other examples are shown where the gate-drain charge parameter Q is selected or highlighted. GD (Q gd Technical information related to the parameter is displayed in the GUI and can be viewed by the user. If technical information exists associated with multiple parameters, and the user selects one of the parameters for which technical information is stored, and then selects another of those parameters, when the second parameter is selected, the technical information associated with the first parameter will no longer be displayed in the GUI. Instead, the technical information associated with the second parameter will be displayed. If the user selects a parameter for which technical information is not stored, the GUI may be prevented from displaying any further technical information already shown to avoid confusion about which parameter the technical information is associated with.

[0048] Some fixed datasheets contain information about the pins of electrical components such as MOSFETs. For example, this information can identify which pins are source pins, drain pins, or gate pins. However, while a user may be able to determine from the datasheet how many source pins, etc., a MOSFET has, it does not help in identifying the role of each individual pin. Furthermore, since each MOSFET can be different, the pin layout of one MOSFET may not be the same as the pin layout of another MOSFET. To address this problem, this GUI can be configured to present information about the pins of electrical components such as MOSFETs. In particular, the GUI can display one or more graphical representations of the electrical component (such as a MOSFET) alongside a table-formatted representation listing the pins. This is called "pinning information." The representation of a MOSFET can be a simplified outline of the MOSFET or a graphic symbol of the MOSFET, such as a circuit diagram. At least one of the pins for which pinning information exists is associated with a corresponding pin displayed in two or more representations of the MOSFET. When a user selects a pin associated with a corresponding pin in a representation (for example, by using a pointer device or by using their finger on a touch-sensitive screen to select the location corresponding to the pin in either representation), the image displayed by the GUI is modified to show the user the corresponding pin in all other representations.

[0049] Figure 4 shows some examples of the displays presented by this GUI, where each pin has pin information that identifies it as a mount base connected to the gate, source, or drain (other information can also be displayed for each pin). This information is shown as data in Table 40. The table has three columns: "Pin", "Symbol", and "Description". Next to the pin information, two graphical representations 41 and 42 of the MOSFET are shown. When the user selects a pin from the pin information on the GUI, the corresponding pin in representations 41 and 42 is identified to the user. Similarly, when the user selects a pin in either representation 41 or 42 of the MOSFET, the associated pin in the other representation and pin information 40 is identified to the user.

[0050] In either case, the instructions may be as shown in Figure 4, where "pin 1" of an electrical component is selected (using either pin information 40 or graphical representations 41, 42), and that pin is highlighted in pin information 40 and graphical representations 40, 41. In Figure 4, the associated pin is identified by graphical highlighting, but it could also be identified in other ways, such as by bolding or circling.

[0051] Figure 5 shows the steps of a first method 500, which is one embodiment of the present invention. In step 501, the value of at least one first parameter is displayed using a GUI, and in step 502, the value of at least one second parameter is displayed using a GUI. These two steps may be performed by a GUI that produces a display having the same general appearance as the fixed datasheet in Figure 1.

[0052] In step 503, as shown in Figures 2A and 2B, user input is received via the GUI to modify the value of at least one first parameter.

[0053] In step 504, as shown in Figure 2B, the corresponding calculated value of the second parameter associated with the modified first parameter (i.e., the second parameter if calculated using the modified first parameter) is displayed.

[0054] Figure 6 shows the steps of a second method 600, which is one embodiment of the present disclosure.

[0055] In step 601, technical information associated with each of one or more parameters of an electrical component is obtained. For example, the data may be obtained from a database portion of a computer program product that stores program instructions for implementing a GUI.

[0056] In step 602, when the user provides user input to the GUI and selects one of the parameters, the GUI displays technical information associated with the selected parameter.

[0057] Figure 7 shows the steps of a third method 700, which is one embodiment of the present disclosure.

[0058] In step 701, data is obtained that associates one or more pins of an electrical component with the pins of two or more corresponding representations of the electrical component displayed on a GUI generated by the computer system. For example, the data may be obtained from a database portion of a computer program product that stores program instructions for implementing the GUI.

[0059] In step 702, when the user provides data input to the GUI and selects a pin in one of the representations of an electrical component, the representation generated by the GUI is modified to identify the associated pin in at least one other representation, for example, by highlighting it.

[0060] A GUI can be implemented as program code executed by a computer system having a processor that operates to execute code and a display device under the control of the processor. The GUI operates to perform any one or more of the methods 500, 600, and / or 600. The GUI may be programmed using HTML, CSS, or JavaScript, or any other programming language may be used.

[0061] The above disclosure provides an interactive datasheet as a GUI, allowing users to dynamically modify the operating parameters of MOSFETs or other electronic components and to identify information related to those parameters. Users can also identify the associated pins of a MOSFET between its representation and pin information on the datasheet. These functions can be implemented individually or in any combination on a single datasheet.
