Technical Field

[0001] The present invention belongs to the technical field of electronic design automation, and in particular relates to an electronic product design rule checking system based on multi-module collaboration. Background Art

[0002] As electronic products develop towards higher integration and smaller size, schematic design becomes more and more complex. Design Rule Check (DRC), as an important part of ensuring the quality of schematic design, faces new challenges. Existing DRC tools usually have several limitations: on the one hand, most DRC tools can only provide preset rule libraries, which are difficult for users to adjust and expand according to their specific needs, which limits the flexibility and adaptability of the tools; on the other hand, many DRC tools only support data input in a specific format, which limits their application in different electronic design automation (EDA) tool environments and reduces the versatility and interoperability of the tools; in addition, the detection reports provided by most tools are not intuitive enough, which is not convenient for quickly locating the problem, which increases the workload of designers; coupled with the lack of effective management means to organize and maintain EDA design resources, such as standard unit circuits, device package libraries, etc., which further affects the efficiency and quality of the design; finally, due to the lack of statistical analysis functions on user behavior, design efficiency, etc., it is difficult to evaluate the design quality and improvement direction, which limits the ability of the design team to make continuous improvements.

[0003] Therefore, in order to meet the growing design needs, a more advanced, flexible and efficient electronic design rule checking system is urgently needed. This system should not only support users to edit the design rule library, but also have strong data compatibility and intuitive detection report display functions, and should also provide effective resource management methods to support various needs in the design process. Summary of the invention

[0012] The circuit information is matched with corresponding standard circuits and disabled circuits in the EDM resource library, and the standard circuits and disabled circuits are output to the core processing module.

[0013] Further, the EDM calling module calls the standard circuits and disabled circuits matching the standardized bill of materials pattern through the HTTP standard protocol;

[0014] Furthermore, the core processing module is also used to determine whether there is a disabled circuit in the schematic diagram based on the standard circuit and the disabled circuit and to count the usage frequency of the standard circuit in the schematic diagram.

[0056] Figure 1 is a module diagram of an electronic product design rule checking system based on multi-module collaboration provided by an embodiment of the present invention, such as Figure 1 As shown, the electronic product design rule checking system based on multi-module collaboration provides five modules, including a BOM processing module, a design checking rule processing module, a core automation processing module, an EDM management module and an EDM calling module.

[0057] The BOM processing module is used to receive and process the bill of materials of the schematic diagram, including but not limited to removing invalid data and standardizing the data format.

[0058] The design check rule processing module is used to read the unstructured design check rule file and convert it into a structured data form to complete persistent storage;

[0059] The core automated processing module is used to automatically perform schematic inspection tasks and output various inspection reports by combining BOM processed data and design inspection rules;

[0060] The EDM management module is used to store and manage design resource libraries such as standard unit circuits and components;

[0061] The EDM calling module is used to implement the calling of standard unit circuits and disabled unit circuits.

[0062] Figure 2 is a prototype architecture diagram of an electronic product design rule checking system based on multi-module collaboration provided by an embodiment of the present invention, such as Figure 2 As shown, the BOM processing module includes operations such as capturing BOM data, data filtering, and standardization processing; the design check rule processing module includes operations such as reading unstructured design check rules, structured processing, and persistent storage; the core processing module includes operations such as automatic rule matching checking, EDM unit single-channel and schematic circuit matching processing, and generating various types of test report operations; the EDM calling module includes operations for extracting standard unit circuits and comparing and extracting disabled unit circuits; terminal management is used for user management, authority management, and EDM design resource library management.

[0063] Figure 3 : is a flow chart of an electronic product design rule checking system based on multi-module collaboration provided by an embodiment of the present invention, and the specific steps are as follows:

[0064] S1, structured storage of the unstructured design inspection rule knowledge base content;

[0065] S2, extract schematic BOM information, filter and standardize;

[0066] S3, custom add, modify or delete some design check rules for automated rule checking;

[0067] Specifically, since the design rule knowledge base was not structured during compilation, the traditional manual inspection method is to check by comparing the design rule knowledge base with the schematic design. However, during automated inspection, the machine cannot accurately process unstructured data types, resulting in biased inspection results and low efficiency. Therefore, the unstructured design rules are first structured and stored. At the same time, the schematic and BOM information uploaded by the user are captured and parsed, and the columns of the BOM table are formatted and escaped to generate standardized BOM data. Automated inspection can begin after the design check rules and schematic design information are available. However, since some rules in the design check rule knowledge base may not be fully adapted to the current project and customized rules are required, automated inspection is performed by adding, modifying or deleting some design check rules.

[0068] S4, triggering the check call check of the standard unit circuit and the disabled unit circuit in the EDM;

[0069] Specifically, the system supports the integration of electronic design automation tools into the EDM design resource management library. In S4, the system automatically triggers the matching call between the unit circuit in the EDM and the circuit in the checked schematic, automatically compares the difference between the standard unit circuit and the circuit in the checked schematic, and detects whether there is a disabled unit circuit in the schematic.

[0070] S5, completes the automatic inspection and generates a schematic detection report, an error rule type statistical analysis report, and a design circuit and standard unit circuit comparison report.

[0071] Specifically, according to the above automatic inspection process, various inspection reports are generated. The schematic inspection report contains the description of the non-standard items in the schematic design and the location of the screenshots; the error rule type statistical analysis report contains the current violation of the design rule type and the historical violation of the design rule type statistical analysis; further. Its function can filter the time period, and then the number of detections and the number of errors in a specific time period.

[0072] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
