[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0053] To facilitate understanding of this embodiment, the embodiments of the present application are described in detail below.

[0054] The present application embodiment provides a method for drawing a circuit schematic diagram, such as Figure 1 As shown, Figure 1 A schematic diagram of a circuit schematic drawing method provided in an embodiment of the present application, the method comprising the following steps:

[0055] S101, obtaining circuit design requirements, and obtaining a first circuit module diagram and a second circuit module diagram according to the circuit design requirements.

[0056] Among them, the first circuit module diagram is used to characterize the properties of each sub-circuit, the function of each sub-circuit and the properties of each component in the target circuit targeted by the circuit design requirements under the first format, and the second circuit module diagram is used to characterize the connection relationship of each component in the target circuit targeted by the circuit design requirements under the first format.

[0057] Specifically, the target circuit targeted by the above circuit design requirements includes multiple sub-circuits, and the circuit designer obtains the first circuit module diagram according to the circuit design requirements. The properties of the sub-circuit represented by the first circuit module diagram include: the input and output characteristics of the sub-circuit, the power consumption of the sub-circuit, the response time of the sub-circuit, the noise performance of the sub-circuit, the durability of the sub-circuit and the stability of the sub-circuit. The functions of the sub-circuit represented by the first circuit module diagram include: the logical operation function of the sub-circuit, the signal processing function of the sub-circuit, the data storage function of the sub-circuit and the interface conversion function of the sub-circuit. The above sub-circuit includes multiple components, and the properties of each component represented by the second circuit module diagram include: the type of component and the value of the component, such as the resistance, capacitance and inductance of the component.

[0058] The circuit designer obtains the second circuit module diagram according to the circuit design requirements. The connection relationship of each component represented by the second circuit module diagram includes: series connection, parallel connection, mixed connection and star connection.

[0059] The first circuit module diagram and the second circuit module diagram can fully characterize the circuit design requirements of the target circuit. Figure 2 As shown, Figure 2 A schematic diagram of the SysML (Systems Modeling Language) model structure provided for an embodiment of the present application. The SysML model is a graphical modeling language that can provide a semantic basis for requirements, behaviors, structures, and parameters (mathematical models) in system modeling, and can integrate other engineering analysis models. The SysML model has been widely used in MBSE (Model-Based Systems Engineering) practices to support the representation, analysis, design, and verification of complex systems. The SysML model includes BDD (Block Definition Diagram), IBD (Internal Block Diagram), UC (Use Case Diagram), ACT (Activity Diagram), SQ (Sequence Diagram), STM (State Machine Diagram), PA (Parametric Diagrams), PKG (Package Diagram) and REQ (Requirement Diagram).

[0060] Among them, the module definition diagram is used to represent structural elements such as modules and the relationship between elements. The internal module diagram is a static (structured) view of the system or a component of the system. The use case diagram is a black box diagram of the system performing specific functions under the operation of the operator. It is used to express the specific functions performed by the system, as well as the incentives and participants when performing specific functions. The activity diagram is used to focus on the control flow, understand and express the behavior that the system should have, and the process of converting input into output. The sequence diagram is used to focus on and accurately describe the interaction between different modules within the system. It is an excellent mechanism for specifying test cases. The state machine diagram is used to focus on a series of states of the modules within the system and the transitions between different states under event triggering. State machine diagram and sequence Figure 1In this way, the behavior of a module can be accurately described and can also be used as input to the development phase of the life cycle. Parameter diagrams are used to define and track system parameters. Package diagrams are used to show the organizational structure and hierarchical relationships of the model, and are used to organize and group elements in the system for easy management and understanding. Requirement diagrams are used to represent text-based requirements, relationships between requirements, and other model elements that verify and refine requirements.

[0061] The first circuit module diagram and the second circuit module diagram are obtained based on the SysML model, so the first format is to adapt the circuit design requirements to the language format specified by the SysML model.

[0062] S102, generating an XML file of a target circuit according to the first circuit module diagram and the second circuit module diagram.

[0063] Specifically, XML (Extensible Markup Language) is a markup language that can be flexibly used to store and transmit data in the Internet and intranet. Therefore, the XML file of the target circuit generated above can be adapted to the storage and transmission format of the SysML model.

[0064] S103, obtaining a netlist of the target circuit according to the XML file.

[0065] The netlist is used to characterize the design of the target circuit. The netlist is obtained according to the above XML file and is also adapted to the storage and transmission format of the SysML model.

[0066] S104: If the design situation meets the circuit design requirements, a circuit schematic diagram of the target circuit is generated according to the netlist.

[0067] Specifically, a circuit schematic is a diagram that uses symbols to represent electronic components and their connection methods. In a circuit schematic, various electronic components, such as resistors, capacitors, transistors, connectors, and integrated circuits, are simplified into specific symbols, and the connecting lines or network labels between these symbols represent the actual electrical connections between the components. During the circuit design stage, circuit designers use circuit schematics to plan and verify the functions of circuits when designing circuits. The circuit schematic generated above can meet the circuit design requirements of the target circuit obtained by the designer. The process of generating a circuit schematic based on the netlist is completely performed by the SysML model, which saves manpower and shortens the drawing time of the circuit schematic.

[0068] The circuit schematic drawing method provided in the embodiment of the present application generates a circuit schematic of a target circuit according to a netlist, and the circuit schematic obtained by the method meets the circuit design requirements of the target circuit. Compared with the method of drawing a large number of components and connecting a large number of networks between components in the schematic drawing page in the prior art, this method does not require designers to perform tedious manual operations, and can accurately draw the circuit schematic of the target circuit, saving human resources, significantly reducing drawing time, and improving work efficiency.

[0069] The following describes the method for determining the first circuit module diagram. Figure 3 As shown, Figure 3 A first circuit module diagram of a circuit schematic drawing method provided in an embodiment of the present application. The method includes: generating subcircuit description information according to circuit design requirements, and generating a first circuit module diagram according to the subcircuit description information. The subcircuit description information includes: the properties of each subcircuit in the target circuit targeted by the circuit design requirements in the second format, the functions of each subcircuit, and the properties of each component.

[0070] Specifically, the first circuit module diagram generated in this method is generated in the BDD of the SysML model. BDD represents the attributes of each sub-circuit based on the sub-circuit description information. For example: the input and output characteristics of the HCE4644 power supply (the input voltage range is 4V-14V and the output voltage range is 0.6V-1.5V). BDD represents the functions of each sub-circuit based on the sub-circuit description information. For example: the differential operation function of the (Low-Voltage Differential Signaling) circuit. BDD represents the attributes of each component based on the sub-circuit description information. For example: the input voltage of the HCE4644 power supply is 12V. In order to adapt the above sub-circuit description information to the language format specified by the BDD, the above sub-circuit description information is displayed in the first circuit module diagram in the second format.

[0071] This method can summarize the circuit design requirements and present them in the form of a first circuit module diagram, thereby making the circuit design requirements specific.

[0072] The following is an introduction to the method of determining the second circuit module diagram. Figure 4 As shown, Figure 4 A second circuit module diagram of a circuit schematic drawing method provided in an embodiment of the present application. The method includes: generating sub-circuit internal description information according to circuit design requirements, and generating a second circuit module diagram according to the sub-circuit internal description information. The sub-circuit internal description information includes: the connection relationship of each component in the target circuit targeted by the circuit design requirements in the second format.

[0073] Specifically, the second module circuit diagram generated in this method is generated in the IBD of the SysML model. IBD displays the relationship and interface between the internal components of the module based on the internal description information of the sub-circuit, that is, the connection relationship between the various components in the target circuit targeted by the circuit design requirements under the second format. For example: in the second module circuit diagram, the interface of X1 includes P1 and P2, the interface of X2 includes P5 and P6, the interface of the K7 minimum system includes GND1, the interface of the LVDS circuit includes the LVDS circuit output terminal P, the LVDS circuit output terminal N and GND2, and the interface of the HCE4644 power supply includes the input voltage and GND3; wherein, P1 is connected to the input voltage, P2 is respectively connected to GND1, GND2 and GND3, P6 is connected to the LVDS circuit output terminal P, and P5 is connected to the LVDS circuit output terminal N.

[0074] The above components are all CBB (Common Building Blocks). CBB is a combination of a series of standardized electronic components that can realize specific circuit functions. The combination and connection method of each electronic component in CBB is usually verified by a large number of experiments and tests, and the function is reliable. CBB can be called repeatedly to build various circuit boards and electronic devices, providing a basis for electronic design and manufacturing, allowing circuit designers to quickly develop complex circuits. In addition, in order to adapt the internal description information of the above sub-circuit to the language format specified by IBD, the internal description information of the above sub-circuit is displayed in the second circuit module diagram in a second format.

[0075] This method can summarize the circuit design requirements and present them in the form of a second circuit module diagram, thereby making the circuit design requirements specific.

[0076] The following is an introduction to the method of obtaining the netlist of the target circuit based on the XML file. Figure 5 As shown, Figure 5 An XML file schematic diagram of a circuit schematic drawing method provided in an embodiment of the present application, the method includes: parsing an XML file to obtain circuit information, and obtaining a netlist based on the circuit information. The circuit information includes: the properties of each sub-circuit in the target circuit targeted by the circuit design requirements under the third format, the functions of each sub-circuit, the connection relationship of each component, and the properties of each component.

[0077] Specifically, in the above manner, in order to adapt the above circuit information to the language format specified by the netlist, the above circuit information is displayed in the netlist in the third format.

[0078] The following is an introduction to the method of generating a circuit schematic diagram of a target circuit based on a netlist. Figure 6 As shown, Figure 6A netlist diagram of a circuit schematic drawing method provided in an embodiment of the present application. The method includes: obtaining symbols of components corresponding to the netlist, creating a blank schematic page, placing the symbols of components on the blank schematic page according to the netlist, and connecting the symbols of components to obtain a circuit schematic of the target circuit.

[0079] Specifically, the format of the above netlist is shown in Table 1.

[0080]

[0081]

[0082] Table 1

[0083] The above SysML model searches for the corresponding symbol in the circuit design resource library according to the CBB Name / Part Name, material code and Symbol name in Table 1, places the symbol of the component in the created blank schematic page, assigns the component according to the number of the symbol in Table 1, completes the interconnection between the components according to the Symbol name, Pin Number and Pin Name information, and names the connection network between the components according to the Net Name information. If the Net Name does not exist, the SysML model automatically assigns the default network name of the connection network to each component.

[0084] This method does not require circuit designers to manually draw component symbols on a blank schematic page, saving manpower and improving work efficiency.

[0085] In one implementation, the method includes: if the design situation does not meet the circuit design requirements, modifying the netlist according to the circuit design requirements.

[0086] Specifically, the circuit design requirements obtained by the circuit designer are compared with the netlist content. If the content in the netlist is inconsistent with the circuit design requirements, it means that an error occurred during the generation of the netlist. Since the circuit schematic needs to be generated based on the netlist, the netlist needs to be modified at this time.

[0087] This method improves the accuracy of the circuit schematic by strictly verifying the correctness of the netlist.

[0088] In one embodiment, the method includes: verifying the circuit schematic diagram to obtain a verification result, and if the verification result shows that there is an error in the circuit schematic diagram, generating an error warning message and marking the error position of the circuit schematic diagram.

[0089] Specifically, in this method, if it is verified that there is an error in the circuit schematic, the error position in the circuit schematic will be marked in red to prompt the circuit designer to modify the red-marked position.

[0090] This method notifies circuit designers to modify the circuit schematic by generating error warning information and marking the error position of the circuit schematic, thereby improving the accuracy of the circuit schematic and the work efficiency of circuit designers.

[0091] Based on the above method embodiment, the present application embodiment provides another circuit schematic drawing method, such as Figure 7 As shown, Figure 7 A schematic flow chart of another circuit schematic drawing method provided in an embodiment of the present application, the method comprising the following steps:

[0092] S701, obtaining circuit design requirements.

[0094] S702, obtaining a first circuit module diagram and a second circuit module diagram according to circuit design requirements.

[0095] Among them, the first circuit module diagram is used to characterize the properties of each sub-circuit, the function of each sub-circuit and the properties of each component in the target circuit targeted by the circuit design requirements under the first format, and the second circuit module diagram is used to characterize the connection relationship of each component in the target circuit targeted by the circuit design requirements under the first format.
