Description

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 move toward higher integration and smaller sizes, schematic design becomes increasingly complex. Design rule checking (DRC), a crucial step in ensuring schematic design quality, faces new challenges. Existing DRC tools often suffer from several limitations. First, most DRC tools only provide a pre-set rule library, making it difficult for users to adapt and expand it to their specific needs. This limits the tool's flexibility and adaptability. Second, many DRC tools only support data input in specific formats, restricting their applicability across diverse electronic design automation (EDA) tool environments and reducing their versatility and interoperability. Furthermore, the inspection reports provided by most tools are not intuitive enough, making it difficult to quickly locate problems, which increases the designer's workload. Furthermore, the lack of effective management tools to organize and maintain EDA design resources, such as standard cell circuits and device package libraries, further impacts design efficiency and quality. Finally, the lack of statistical analysis capabilities for user behavior and design efficiency makes it difficult to assess design quality and identify improvement areas, limiting the design team's ability to continuously improve.

[0003] Therefore, to meet the growing design demands, a more advanced, flexible, and efficient electronic design rule checking system is urgently needed. Such a system should not only support user-defined editing of the design rule library, but also have strong data compatibility and intuitive inspection report display capabilities. At the same time, it should also provide effective resource management to support various needs in the design process. Summary of the Invention

[0056] Figure 1 FIG 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. Figure 1 As shown, the electronic product design rule checking system based on multi-module collaboration provides five modules, including BOM processing module, design check rule processing module, core automation processing module, EDM management module and 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 structured data form for 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 This 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. Figure 2 As shown, the BOM processing module includes capturing BOM data, data filtering, and standardization processing operations; the design check rule processing module includes reading unstructured design check rules, structured processing, and persistent storage operations; the core processing module includes automatic rule matching inspection, EDM unit single-channel and schematic circuit matching processing, and generation of various test report operations; the EDM call 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 This 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. 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, customize the addition, modification or deletion of some design check rules for automated rule checking;

[0067] Specifically, since the design rule knowledge base was not structured when it was compiled, 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 and inefficient inspection results. 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 inspection rules and schematic design information are available. However, since some rules in the design inspection 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 inspection rules.

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

[0069] Specifically, the system supports electronic design automation tools integrated with EDM design resource management libraries. In S4, the system automatically triggers the matching call of unit circuits in the EDM with the circuits in the schematic being checked, automatically compares the differences between standard unit circuits and the circuits in the schematic being checked, and detects whether disabled unit circuits appear in the schematic.

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

[0071] Specifically, various inspection reports are generated based on the automated inspection process described above. The schematic inspection report includes a description of any irregularities in the schematic design and screenshots of their locations. The error rule type statistical analysis report includes a statistical analysis of current and historical design rule violation types. Furthermore, the system can filter time periods to identify the number of inspections and errors within a specific time period.

[0072] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure.
