Description

Technical Field

[0001] The present invention relates to the field of circuit simulation technology, and in particular to a method, device, storage medium and equipment for modeling, simulating and analyzing a circuit diagram. Background Art

[0002] Modeling and simulation software is a tool used to simulate and analyze system performance. Through modeling and simulation software, designs can be tested and evaluated without actually building or manufacturing physical prototypes, reducing expensive physical testing and unnecessary iterations, thereby effectively improving verification efficiency while reducing verification costs and risks, making modeling and simulation software an irreplaceable engineering simulation software and teaching software. In actual use, users can observe the circuit status at any time through the rich electronic components provided by modeling and simulation software, such as power supplies, resistors, inductors, pulleys, etc., by simply setting component parameters and simulation time. Among them, the more famous modeling and simulation software include Modelica, Matlab, Simulink, etc.

[0003] However, different modeling and simulation software usually use their own unique data formats to represent circuit diagram data. These data formats are often tailored for specific software or simulation environments, focusing on meeting the internal needs of the software and optimizing performance. Although this proprietary data format design has improved the operating efficiency of the software to a certain extent, it also brings obvious limitations. When users need to migrate circuit design data to a new simulation environment or integrate with other software, the existing data format is often difficult to directly expand or adapt, resulting in users needing to re-model, which greatly increases the cost of simulation analysis.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this specification will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0020] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0021] Figure 1 A schematic diagram of a modeling and simulation analysis method for a circuit diagram provided in this specification includes the following steps: S101: displaying a preset model library in a preset graphical interface, and obtaining layout operation instructions executed by the user for different models included in the model library, wherein the models are used to represent electronic components required to construct a circuit diagram.

[0022] In this specification, the business platform can provide a preset model library to the user through a preset graphical interface, so that the user can execute layout operation instructions such as dragging, text editing, and clicking for different models contained in the model library in the graphical interface, and then the model selected by the user can be determined according to the layout operation instructions sent by the user, and the definition data configured by the user for the selected model can be determined, and then the target circuit diagram can be constructed in the circuit diagram drawing canvas according to the model selected by the user and the definition data of the model, and simulation analysis can be performed based on the constructed target circuit diagram.

[0023] Among them, the above-mentioned model may refer to the symbols pre-provided by the business platform to users for representing the electronic components required to construct circuit diagrams, as well as the wiring tools used to connect these electronic components. The electronic components here may be, for example: power supplies, resistors, capacitors, transistors, etc.

[0024] The definition data of the above-mentioned model may refer to data used to describe the basic properties of the electronic components corresponding to the model in circuit design and simulation, as well as necessary information such as the connection method of the model, such as: component name, manufacturer name, model, electrical characteristic parameters (such as resistance, rated power, capacitance, withstand voltage, etc.), size, pin layout (a model can have multiple pins for connecting with other models, and the pins here can refer to the metal joint points on the model), connection method, etc.

[0025] It should be noted that among the models included in the model library, the definition data of some models may be fixed, and of course, the definition data of some models may be customized by users. In this case, the business platform can set basic definition data for each model in the model library, so that when the user needs to customize the definition data of at least some of the selected models, the user can execute the layout operation instructions for the model requiring customized definition data in the graphical interface based on the basic definition data of the model requiring customized definition data, so as to obtain the modified definition data of the model requiring customized definition data, so that the business platform can construct the target circuit diagram according to the modified definition data of the model.

[0026] In this specification, the execution entity used to implement the modeling, simulation and analysis method of the circuit diagram may refer to a designated device such as a server set up on a business platform, or may refer to a terminal device such as a desktop computer or a laptop computer. For the sake of ease of description, the modeling, simulation and analysis method of the circuit diagram provided in this specification is described below using the server as the execution entity as an example.

[0027] S102: Construct a target circuit diagram according to the layout operation instruction, and parse the target circuit diagram to obtain graph basic data corresponding to the target circuit diagram; each node in the graph basic data is used to represent each graph element included in the target circuit diagram, and the graph elements include: electronic components and connections between electronic components; each edge in the graph data is used to represent the connection relationship between two graph elements.

[0028] It should be noted that in this specification, component entities, lines, and connection points included in different circuit diagrams may be represented by component entities representing data, lines representing data, and connection points representing data.

[0029] Among them, the component entity can refer to an electronic component extended from the model for drawing actual circuit diagrams. The component entity has multiple pins for connecting between component entities. The pins here can be metal connectors on the entity for connecting different component entities.

[0030] In the above content, lines can refer to the connections between various electronic components in the circuit diagram. These lines can be straight lines, curves, broken lines or other forms. Their role in the circuit diagram is to show the flow direction and connection relationship of current, signal or power supply.

[0031] In the above content, a joint point can refer to the connection point of two or more wires or conductors in a circuit. A joint point can be a physical connection between different parts or components in a circuit, which allows current or signals to pass from one part to another.

[0032] From the above content, it can be seen that through the above circuit structure data, a data representation of a complex circuit diagram can be completely defined. For ease of understanding, the following is combined Figure 2 The above-mentioned circuit configuration data will be described in detail.

[0033] Figure 2 This is a schematic diagram of the circuit structure data provided in this manual.

[0034] Combination Figure 2 It can be seen that for each component entity data Entity, it can include attributes such as model definition data Model and pins Pins, and for each line representation data Edge, it can include attributes such as the start connection point Start Joint and the end connection point End Joint.

[0035] From the above content, it can be seen that the server can represent the target circuit diagram through component entity representation data Entity, line representation data Edge, and connection point representation data Joints.

[0036] Based on this, the server can construct a target circuit diagram according to the layout operation instructions executed by the user in the graphical interface, and then analyze the target circuit diagram to obtain circuit structure data corresponding to the target circuit diagram.

[0037] Furthermore, after obtaining the circuit structure data corresponding to the target circuit diagram, the server can convert each node contained in the target circuit diagram and the node characteristics of each node according to the circuit structure data to obtain the graph basic data corresponding to the target circuit diagram, and then store the graph structure of the target circuit diagram through the graph data.

[0038] Specifically, the server can create a node corresponding to each diagram element contained in the target circuit diagram according to the component entity representation data or line representation data of the diagram element, and then determine the node characteristics of the node corresponding to the diagram element according to the attributes of the component entity representation data or line representation data of the diagram element and the connection point representation data contained in the diagram element.

[0039] Among them, for each graphic element corresponding to an electronic component included in the target circuit diagram, if the connection point representation data contained in the graphic element is consistent with the connection point representation data contained in the graphic element corresponding to the connection between the electronic components, it can be considered that the graphic element and the graphic element corresponding to the connection between the above-mentioned electronic components are connected through the connection point corresponding to the connection point representation data contained in the graphic element. At this time, it can be determined that the node used to represent the graphic element in the above-mentioned basic graph data and the node used to represent the graphic element corresponding to the connection between the above-mentioned electronic components are connected through an edge. By analogy, the server can convert and store the basic graph data corresponding to the target circuit diagram based on the circuit structure data.

[0040] In actual application scenarios, the formats of netlist data used by different simulation and analysis programs are often different, such as SPICE netlist, Verilog netlist, EDIF netlist, etc. At this time, the server can also pre-set a conversion program for converting the basic diagram data into the netlist data in that format for each format of netlist data, so that when receiving the simulation and analysis instructions for the target circuit diagram, the format of the netlist data to be converted can be determined according to the simulation and analysis instructions as the target format, and then the conversion program matching the target format can be determined from the preset conversion programs, and the basic diagram data can be converted into the netlist data required for interaction with the simulation and analysis program through the conversion program matching the target format.

[0041] It should be noted that the simulation analysis tasks performed by users when performing simulation analysis on different circuit diagrams may be different (for example, in the circuit performance simulation analysis task, it is necessary to simulate and analyze the basic parameters of the circuit, such as voltage, current, and power. In the signal integrity simulation analysis task, it is necessary to analyze the transmission quality of the signal in the circuit, including reflection, crosstalk, attenuation, etc.), and the execution logic of different simulation analysis tasks is often different. Therefore, it is often necessary to deploy code programs for executing different task logics in the server, which makes it often difficult to manage and maintain these code programs.

[0042] Therefore, in this specification, the code programs of the above-mentioned different task logics and the conversion programs in the above-mentioned content can be deployed in different processors, and these processors can be stored through a chain structure, so that the server can generate a task request according to the received simulation analysis instructions for the target circuit diagram when receiving the simulation analysis instructions for the target circuit diagram, and send the task request to each processor in sequence along the sequence between the processors included in the preset processing flow chain until the task request is sent to the target processor that matches the task request, so that the target processor determines the port number representation corresponding to each electronic component contained in the graph basic data according to the edges contained in the graph basic data.

[0043] S103: upon receiving a simulation analysis instruction for the target circuit diagram, determining the port number representation corresponding to each electronic component contained in the basic data of the diagram according to the edges contained in the basic data of the diagram, wherein the port number representation is used to characterize the connection relationship between the electronic components.

[0044] S104: According to the diagram basic data and the port number representation, convert the diagram basic data into the netlist data required for interacting with the simulation analysis program, so that the simulation analysis software performs simulation analysis on the target circuit diagram based on the netlist data.

[0045] In this specification, when the server determines that simulation analysis needs to be performed on a target circuit diagram, it can obtain the graph basic data corresponding to the target circuit diagram, and then determine the port number representation corresponding to each electronic component included in the target circuit diagram based on the edges contained in the graph basic data, and then, based on the graph basic data and the port number representation corresponding to each electronic component included in the target circuit diagram, the graph basic data can be converted into the netlist data required for interacting with the simulation analysis program, so as to perform simulation analysis on the target circuit diagram based on the netlist data.

[0046] There may be multiple conditions under which the server determines that simulation analysis needs to be performed on the target circuit diagram. For example, when a simulation analysis instruction for the target circuit diagram is received, a task request can be generated based on the simulation configuration parameters set by the user (such as simulation time, simulation step, analysis type, etc.), and then the server can determine that simulation analysis needs to be performed on the target circuit diagram based on the task request.

[0047] For another example, when a user inputs or adjusts simulation configuration parameters in a graphical interface, the server can automatically determine that simulation analysis needs to be performed on the target circuit diagram when detecting changes in these parameters.

[0048] In the above content, the method for determining the port number representation corresponding to each electronic component included in the target circuit diagram according to the edges included in the graph basic data can be that the server selects the first target node (i.e., the node used to characterize the electronic component) from each node of the graph basic data, and then constructs an instance object (each instance object is used to characterize each electronic component in the target circuit) according to the node characteristics of the first target node, and determines the connection points contained in the instance object, and then assigns port numbers to the connection points contained in each instance object according to the order of the connection points contained in each instance object.

[0049] Furthermore, the server can determine the port number representation corresponding to each electronic component contained in the graph basic data according to the port number of the connection point contained in each instance object, as shown in the following example: Figure 3A shown.

[0050] Figure 3A A schematic diagram of the port numbers of the connection points provided in this manual.

[0051] exist Figure 3A The target circuit diagram shown includes four electronic components, namely, a single-phase sinusoidal AC voltage source, a resistor, an ammeter, a voltage probe, and a special component grounding. Among them, the single-phase sinusoidal AC voltage source includes 2 connection points, the voltage probe includes 1 connection point, the resistor includes 2 connection points, the ammeter includes 2 connection points, and the grounding includes 1 connection point.

[0052] At this time, the server can select the first target nodes corresponding to the single-phase sinusoidal AC voltage source, resistor, ammeter, and voltage probe from each node of the graph basic data, and construct the instance object of the single-phase sinusoidal AC voltage source, the instance object of the resistor, the instance object of the ammeter, and the instance object of the voltage probe according to the node characteristics of the first target node, and determine the connection points contained in each instance object. Then, port numbers can be assigned to the connection points contained in each instance object according to the sequence between the connection points. Figure 3A The single-phase sinusoidal AC voltage source shown in the figure includes a connection point with port number 1 and a connection point with port number 2, the voltage probe includes a connection point with port number 3, the resistor includes a connection point with port number 4 and a connection point with port number 5, and the ammeter includes a connection point with port number 6 and a connection point with port number 7.

[0053] The sequence between the joint points may refer to the sequence of traversing each joint point of different instance objects.

[0054] In the above content, according to the sequence between the connection points, the method of allocating port numbers to the connection points contained in each instance object can be to allocate port numbers to the connection points contained in each instance object in sequence in an ascending manner according to the sequence between the connection points.

[0055] Furthermore, after the server assigns port numbers to the connection points contained in each instance object in turn, it is also necessary to linearly recursively traverse each second target node in the graph basic data to determine, for each instance object, other instance objects connected to the instance object through the line represented by the second target node, and determine from the connection points of the instance object the connection point used to connect with other instance objects, and reset the port number of the connection point of the instance object and the port number of the connection points of other instance objects to the same port number.

[0056] The reset port number is used to indicate that the instance object and other instance objects are connected to each other via the connection point corresponding to the reset port number.

[0057] Furthermore, the server can determine the port number representation corresponding to each electronic component contained in the graph basic data according to the port number of the connection point contained in each reset instance object. Figure 3B shown.

[0058] Figure 3B A schematic diagram of the port number of a connection point after reset provided in this specification.

[0059] Combination Figure 3B It can be seen that for the instance object corresponding to the single-phase sinusoidal AC voltage source, the connection point with port number 1 of the instance object is connected to the connection point with port number 3 of the instance object corresponding to the voltage probe and the connection point with port number 4 of the instance object corresponding to the resistor through a connecting line. At this time, the above-mentioned connection point with port number 1, the connection point with port number 3, and the connection point with port number 4 can be used as connection points, and then the port numbers corresponding to the above-mentioned three connection points can be reset to the same port number to represent that the instance object corresponding to the above-mentioned single-phase sinusoidal AC voltage source, the instance object corresponding to the voltage probe, and the instance object corresponding to the resistor are connected through connecting lines and the connection points corresponding to the above-mentioned reset port numbers.

[0060] Specifically, the server can determine the port number of the connection point of the instance object corresponding to the single-phase sinusoidal AC voltage source as the reset port number of the above-mentioned three connection points according to the order between the instance objects, that is, the port numbers of the connection points with port number 3 and the connection points with port number 4 are set to 1.

[0061] It should be noted that, for each electronic component, when a certain connection point in the electronic component is connected to other connection points of the electronic component through a connection line, the connection point used to connect to the connection line is the connection point.

[0062] In addition, in actual application scenarios, the circuit diagrams drawn by users often contain special components, such as grounding, input and output ports, etc.

[0063] At this time, the server can also reset the port number of the instance object of the specified type to a specified value (the above-mentioned specified value can be set according to actual needs, for example: 0) when it is determined that there is an instance object of the specified type in each instance object. Then, based on the reset port number, the server can determine the port number representation corresponding to the electronic component matching the instance object of the specified type contained in the graph basic data, and determine the port number representation corresponding to each electronic component contained in the graph basic data based on the port number of the connection point contained in each re-determined instance object.

[0064] It is worth noting that, for each electronic component, the port number of the electronic component is used to characterize the connection relationship between the electronic component and other electronic components.

[0065] For example: Figure 3B In the figure, the single-phase sinusoidal AC voltage source is connected to other electronic components through the connection point with port number 1 and the connection point with port number 2. At this time, the port number representation of the single-phase sinusoidal AC voltage source is (1,2). By analogy, it can be known that the port number representation of the resistor is (1,5). Furthermore, according to the port number representation of the single-phase sinusoidal AC voltage source and the port number representation of the resistor, it can be known that the single-phase sinusoidal AC voltage source is connected to the connection point with port number 1 in the resistor through the connection point with port number 1 and the connecting line.

[0066] Furthermore, the server may convert the graph basic data into netlist data required for interaction with the simulation analysis program according to the graph basic data and the port number representation.

[0067] For example, part of the netlist data used to characterize the above-mentioned single-phase sinusoidal AC voltage source may be {"label":"AC","name":"AC1","index":1","type":"ELECTRIC","ports":[1,2]}, and so on, to obtain the netlist data used to characterize the target circuit diagram.

[0068] It should be noted that the above-mentioned netlist data may include: nodes (Elements), ports (Ports), attributes (Attributes) and other feature components.

[0069] Among them, nodes are used to represent various logic gates, devices, input and output ports in the circuit. Each node has a unique identifier and name, which is used to correspond to the basic elements in the target circuit diagram.

[0070] Ports are used to represent the connections between nodes in a circuit. The number of ports indicates the number of connection points. When the port numbers are the same, it means that they are connected in the circuit.

[0071] In addition, the attributes of each node or connection in the netlist data are used to describe additional information such as the characteristics, functions, physical location, etc. of the node or connection.

[0072] For example, nodes can have different logical functions (such as AND, OR, NOT, etc.), or can have different basic properties (switch closure state, resistance, capacitance, etc.).

[0073] For ease of understanding, the following describes in detail the calling relationship in the simulation analysis process using the above-mentioned circuit diagram modeling simulation analysis method. Figure 4 shown.

[0074] Figure 4 This is a schematic diagram of the process of circuit diagram simulation analysis provided in this specification.

[0075] Combination Figure 4 It can be seen that the user can execute layout operation instructions for different models contained in the model library in the graphical interface, select different electronic components and connect the electronic components after configuring the definition data of each electronic component, so as to construct the target circuit diagram in the circuit diagram drawing canvas provided in the graphical interface.

[0076] The server can parse the target circuit diagram drawn by the user by calling the server process, obtain the basic diagram data corresponding to the target circuit diagram and store it.

[0077] Furthermore, when the server determines that it needs to perform simulation analysis on the target circuit diagram, it can call the server-side process to convert the basic diagram data corresponding to the target circuit diagram into the netlist data required for interacting with the simulation analysis program. Then, the computing-side process can be called to perform simulation analysis based on the netlist data corresponding to the target circuit diagram and obtain the simulation analysis results.

[0078] It should be noted that the above simulation analysis results may be time series representation data, that is, calculation results used to characterize the change of target parameters (such as current, voltage) over time within a specified time period.

[0079] It can be seen from the above method that the server can convert the target circuit diagram drawn by the user in the graphical interface into a form of graphic data that is independent of the specific simulation analysis program and store it as an intermediate representation. This can support the user's editing operations in the graphical interface and intuitively represent the topological structure between the electronic components in the target circuit diagram and the basic properties of the electronic components. At the same time, when simulation analysis is required, it can be converted into netlist data in different formats supported by different simulation analysis software, so as to facilitate flexible data exchange among different simulation analysis software and different functional modules, thereby effectively reducing the cost of simulation analysis.

[0080] The above is one or more circuit diagram modeling and simulation analysis methods implemented in this specification. Based on the same idea, this specification also provides a corresponding circuit diagram modeling and simulation analysis device, such as Figure 5 shown.

[0081] Figure 5 A schematic diagram of a circuit diagram modeling simulation analysis device provided in this specification includes: An acquisition module 501 is used to display a preset model library in a preset graphical interface and acquire layout operation instructions executed by a user for different models included in the model library, the models being used to represent electronic components required for constructing a circuit diagram, and wiring tools for connecting the electronic components; The conversion module 502 is used to construct a target circuit diagram according to the layout operation instruction, and parse the target circuit diagram to obtain graph basic data corresponding to the target circuit diagram; each node in the graph basic data is used to represent each graph element included in the target circuit diagram, and the graph elements include: electronic components and lines between electronic components; each edge in the graph data is used to represent the connection relationship between two graph elements; A determination module 503 is used to determine, upon receiving a simulation analysis instruction for the target circuit diagram, a port number representation corresponding to each electronic component contained in the graph basic data according to the edges contained in the graph basic data, wherein the port number representation is used to characterize a connection relationship between the electronic components; The simulation analysis module 504 is used to convert the basic diagram data into the netlist data required for interacting with the simulation analysis program according to the basic diagram data and the port number representation, so that the simulation analysis software can perform simulation analysis on the target circuit diagram based on the netlist data.

[0082] Optionally, the conversion module 502 is specifically used to determine at least one model selected by the user according to the layout operation instruction, and determine definition data of the model, wherein the definition data is used to characterize basic attribute data of the model and a connection method of the model; and construct a target circuit diagram in a preset circuit diagram drawing canvas according to the definition data of the model.

[0083] Optionally, the conversion module 502 is specifically used to parse the target circuit diagram to obtain circuit structure data for characterizing the target circuit diagram, the circuit structure data including: component entity representation data, line representation data, connection point representation data; based on the circuit structure data, each node contained in the target circuit diagram and the node characteristics of each node are converted to obtain the graph basic data corresponding to the target circuit diagram.

[0084] Optionally, the determination module 503 is specifically used to generate a task request when receiving a simulation analysis instruction for the target circuit diagram; when it is determined according to the task request that simulation analysis needs to be performed on the target circuit diagram, the task request is sent to each processor in sequence along the sequence between the processors included in the preset processing flow chain, until the task request is sent to the target processor that matches the task request, so that the target processor determines the port number representation corresponding to each electronic component included in the graph basic data according to the edges included in the graph basic data; wherein different processors in the processing flow chain are used to respond to different task requests and perform different simulation analysis tasks.

[0085] Optionally, the determination module 503 is specifically used to select a first target node from each node of the graph basic data, wherein the first target node is used to characterize an electronic component; construct an instance object based on the node characteristics of the first target node, and determine the connection points contained in the instance object; assign a port number to each connection point based on the sequence between the connection points; and determine the port number representation corresponding to each electronic component contained in the graph basic data based on the port number of each connection point.

[0086] Optionally, the determination module 503 is specifically used to linearly recursively traverse each second target node in the graph basic data to determine, for each instance object, other instance objects connected to the instance object through the line represented by the second target node, and determine the connection point used to connect with the other instance objects from each connection point of the instance object; reset the port number of the connection point of the instance object and the port number of the connection point of the other instance object to the same port number; wherein the reset port number is used to represent that the instance object and the other instance objects are connected to each other through the connection point corresponding to the reset port number; and determine the port number representation corresponding to each electronic component contained in the graph basic data according to the reset port number.

[0088] This specification also provides a computer-readable storage medium, which stores a computer program, which can be used to execute the above Figure 1 A modeling, simulation and analysis method for circuit diagrams is provided.

[0089] This manual also provides Figure 6 The one shown corresponds to Figure 1 A schematic diagram of the electronic device. Figure 6 As mentioned above, at the hardware level, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile memory, and may also include other hardware required for the business. The processor reads the corresponding computer program from the non-volatile memory into the memory and then runs it to achieve the above Figure 1 Of course, in addition to the software implementation, this specification does not exclude other implementations, such as logic devices or a combination of software and hardware, etc., that is, the execution subject of the following processing flow is not limited to each logic unit, but can also be hardware or logic devices.

[0090] For the improvement of a technology, it can be clearly distinguished whether it is a hardware improvement (for example, improvement of the circuit structure of diodes, transistors, switches, etc.) or a software improvement (improvement of the method flow). However, with the development of technology, many improvements of the method flow today can be regarded as direct improvements of the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be implemented with a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming themselves, without having to ask chip manufacturers to design and make dedicated integrated circuit chips. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one kind of HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0091] The controller may be implemented in any suitable manner, for example, the controller may take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (e.g., software or firmware) executable by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, and the memory controller may also be implemented as part of the control logic of the memory. It is also known to those skilled in the art that, in addition to implementing the controller in a purely computer-readable program code manner, the controller may be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, such a controller may be considered as a hardware component, and the devices for implementing various functions included therein may also be considered as structures within the hardware component. Or even, the devices for implementing various functions may be considered as both software modules for implementing the method and structures within the hardware component.
