DETAILED DESCRIPTION

[0019] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0020] In the prior art, the following problems exist in the integrated circuit or PCB design process: (1) Mechanical repetitive inspections take up a lot of time, resulting in low design efficiency and extending the overall development cycle; (2) Manual repetitive checks are prone to omissions, unstable design quality, and may introduce errors; (3) The limited design period makes it difficult to carry out some inspections, which affects the design integrity and may lead to potential problems; (4) The inspection work is tedious and monotonous, which makes designers easily fatigued and distracted, increases the rate of human errors, and affects the accuracy of design; (5) The lack of standardization in manual inspection may lead to inconsistent inspection results among different designers, making it difficult to ensure uniform standards for design quality; (6) The lack of real-time feedback during the inspection process leads to a time lag between problem discovery and correction, low efficiency of design iteration, and increased likelihood of rework; (7) The inspection process is difficult to quantify and track, which makes it difficult to objectively evaluate the design quality, and quality management and continuous improvement face challenges; The design rule checking method for PCB design provided in this application can save designers' error checking cycles to the maximum extent and devote more energy to creative work.

[0021] The following describes the design rule checking method, device and equipment for PCB design provided by the present application in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, the present application provides a design rule checking method for PCB design, the method comprising: S101, extracting design data from a design engineering file; wherein the design engineering file includes integrated circuit and PCB data; It is understandable that if Figure 2 As shown, the design engineering file in the present application pre-stores integrated circuit and PCB data. When electrical design or integrated circuit design or PCB data is required, the required design data can be extracted from the design engineering file for subsequent design.

[0023] S102, arranging the design data according to the design rules in the pre-configured rule library to obtain a design result; In some embodiments, before arranging the design data, the method further includes: The extracted design data is converted into a preset data structure; wherein the data structure matches the preset inspection rules.

[0024] Specifically, after the design data is extracted, the extracted design file data is converted into a more efficient and easier to process internal data structure, thereby improving data processing efficiency, optimizing memory usage, accelerating the design rule checking algorithm, and facilitating the implementation of complex checking logic.

[0025] Then, the design data is organized and categorized, and process-specific design rules are imported or set up. These rules define various geometric and electrical constraints.

[0026] S103, checking the design result according to preset checking rules to obtain an inspection report; the inspection report includes the design position that does not meet the design rules; After getting the design results, the check logic is executed, and the software scans and analyzes the entire design according to the loaded rules. After the check is completed, a detailed violation report is generated, listing all places that do not meet the design rules. Designers can view the report and quickly locate and check each violation point. Click in the check result to jump to the corresponding violation location, and in most cases there will be auxiliary animations to allow users to understand the cause / location of the error more clearly and vividly.

[0027] S104, modifying the design positions that do not meet the design rules to obtain a final design result.

[0028] According to the report, designers can make modifications directly at the positioning point without having to switch back and forth between different software.

[0029] In some embodiments, the design rules include: Electrical rules, thermal design, safety and security design, DFM rules and statistical reports.

[0030] Among them, electrical rule checking is mainly used to verify whether the design of integrated circuit (IC) or printed circuit board (PCB) complies with predefined electrical rules. The core of electrical rule automatic checking technology lies in its automation and comprehensiveness. Through predefined rule bases and complex algorithms, electronic designs are scanned and analyzed in an all-round way. Potential electrical problems such as short circuits, open circuits, signal interference, etc. can be identified in the early stages of the design process, thereby improving the reliability and performance of the design. Automated checking can not only significantly reduce human errors, but also handle complex design situations that are difficult for humans to deal with. By quickly and accurately discovering defects in the design, electrical rule automatic checking technology effectively shortens the design cycle and reduces development costs. More importantly, it provides designers with a powerful tool that allows them to focus on innovation and optimization rather than tedious manual checking work.

[0031] Among them, the main inspection items of electrical rule inspection include: Electrostatic Discharge (ESD) protection: Check whether all I / O pins have appropriate ESD protection structures and verify whether the size of the ESD protection circuit is sufficient.

[0032] Latch-up protection: Check whether the substrate and well connections are correct and verify the placement of protection diodes.

[0033] Antenna effect check: Identify long metal lines that may accumulate charge during the manufacturing process and ensure appropriate protection diodes are added.

[0034] Current density check: Verify whether the metal line width is sufficient to carry the expected current, and check the current carrying capacity of vias and contacts.

[0035] IR drop analysis: Check the voltage drop of power and ground networks and identify possible voltage drop hot spots.

[0036] Static Timing Analysis (STA) related checks: verify buffer insertion on critical paths and check the balance of the clock tree.

[0037] Signal integrity check: Identify possible crosstalk issues, check repeater placement on long signal lines.

[0038] Power integrity check: Verify placement of decoupling capacitors, check connectivity of power domains and ground planes.

[0039] Multi-voltage domain check: Verify the correct use of level shifters and check the isolation between different voltage domains.

[0040] As an example, for example, when checking the high-speed line span splitting, it is necessary to configure the name recognition rules of the "high-speed network" in the "network definition" of the platform. The program will match all the high-speed networks that need to be checked in the current brd according to the recognition rules defined here, and check whether these networks have routing in the trenches of the split plane in the adjacent reference layer, and find and report them.

[0041] For thermal design checking, the thermal design checking function is an important part of the electronic design automation checking process, focusing on analyzing and verifying the thermal performance in electronic design. This function is essential to ensure the reliability and performance of electronic products. The core purpose of the thermal design checking function is to identify and prevent thermal problems that may occur in electronic design. This technology combines thermal principles and electronic engineering knowledge to simulate and analyze heat distribution and heat transfer in circuits through complex algorithms. It can help designers discover potential hot spots in the early stages of design, optimize component layout, and ensure that the overall heat dissipation performance meets requirements.

[0042] Among them, the main inspection items of thermal design include: Hot Spot Detection: Identify areas in a circuit that may overheat.

[0043] Temperature distribution analysis: simulate the temperature distribution of the entire circuit board or chip.

[0044] Heat dissipation path verification: Check the effectiveness of the heat dissipation design, such as whether the layout of the heat sink and heat dissipation holes is reasonable.

[0045] Power density analysis: Evaluate whether the power consumption per unit area exceeds the safety threshold.

[0046] Thermal Stress Analysis: Predict the mechanical stresses that may result from temperature changes.

[0047] Material compatibility check: Ensure that the selected material can withstand the expected operating temperature.

[0048] Understandably, the advantage of thermal design checking is that it can detect potential thermal problems in advance and avoid failures in actual production. This not only improves product reliability, but also optimizes performance and extends device life. At the same time, it can help designers make more informed decisions, such as choosing the right package type or adjusting component layout, thereby reducing costs while ensuring performance. During use, designers can set temperature thresholds, define thermally sensitive areas, and even simulate thermal performance under different working environments according to specific project requirements. This flexibility allows thermal design checking to adapt to various complex design requirements. As electronic devices become increasingly miniaturized and high-powered, the importance of thermal management has become increasingly prominent. The thermal design checking function in DRC provides designers with a powerful tool to help them fully consider thermal performance in the early stages of design, thereby developing more reliable and efficient electronic products.

[0049] As an embodiment, for example, when designing a thermal insulation pad when connecting a large area of ​​copper, for the pins of the power ground network, the sum of the widths of the leads on each layer is multiplied by the thickness of each layer to obtain the total area, and the total area threshold size is set (this area is basically directly proportional to the heat dissipation capacity) to judge errors and warnings.

[0050] For safety and regulatory design, the automatic safety and regulatory design check function is a key tool in the electronic product design process to ensure that the product meets safety standards and regulatory requirements. This function helps designers identify and solve potential safety hazards during the design stage to ensure that the product meets various safety regulations and certification requirements. The core of the automatic safety and regulatory design check function lies in its comprehensiveness and preventive nature. It combines electronic engineering knowledge, safety standard requirements and automated detection technology to systematically analyze all aspects of the design to ensure compliance with relevant safety regulations. This not only improves product safety, but also speeds up the certification process and reduces the cost and time of later modifications.

[0051] Among them, the main inspection items for safety and safety design include: Clearance and creepage distance checks: Ensure that the distances between conductive parts meet safety standards to prevent arcing and leakage.

[0052] Insulation strength verification: Check whether the insulation design of the high-voltage part meets the requirements.

[0053] Ground Continuity Check: Verifies that all components requiring grounding are properly connected to the grounding system.

[0054] Overcurrent protection analysis: Check whether the circuit has proper fuse or circuit breaker design.

[0055] (Electro Magnetic Compatibility, EMC) pre-check: Analyze whether the design may have electromagnetic interference or sensitivity problems.

[0056] Material safety verification: Ensure that the selected materials meet safety requirements such as flame retardancy and non-toxicity.

[0057] Thermal safety check: Analyzes possible hot spots to ensure that temperatures do not exceed safety thresholds.

[0058] Labeling and warning checks: Verify that necessary safety labels and warnings are included in the design.

[0059] Industry-specific standards compliance checks: Checks are performed based on specific requirements of different industries (e.g. medical, automotive, aviation).

[0060] Safety and security design checks can detect problems in advance: potential safety hazards can be identified during the design phase to avoid problems in the production or market phase.

[0061] Accelerate the certification process: With automated checks, the documentation and evidence required for certification can be prepared faster.

[0062] Reduced costs: Reduces the need for late modifications and rework, thereby reducing overall development costs.

[0063] Improve design efficiency: Designers can quickly obtain feedback and perform iterative optimization.

[0064] Strong adaptability: Customized inspections can be performed according to the specific requirements of different countries, regions or industries.

[0065] When using this feature, designers can select the applicable safety standard (such as IEC, UL, CE, etc.), and the system will automatically perform the corresponding checks based on the selected standard. In addition, the tool also allows users to add customized safety rules to meet specific product or company requirements.

[0066] As an embodiment, when the anti-pad or the keep-out area of ​​the mounting hole is located, the mounting hole is identified by the aperture and the network, and the size of the anti-pad is prompted. If there is no anti-pad in a certain stack, a warning is issued.

[0067] As for DFM rule checking, the DFM (Design for Manufacturing) rule checking function is a key component of the DRC tool, which integrates manufacturing considerations into the early stages of the design process. The core of this function lies in its predictive and optimization capabilities, which systematically analyzes the design solution, predicts problems that may occur in the production process, and provides corresponding optimization suggestions.

[0068] DFM rule checking is not just a simple verification tool, it is more like a bridge between designers and manufacturing engineers. Through automation, it converts complex manufacturing process requirements into actionable design rules, helping designers to think creatively while taking into account realistic manufacturing limitations. This approach significantly improves the manufacturability of the design, reduces repeated modifications between design and manufacturing, and thus speeds up the entire process from product concept to mass production.

[0069] More importantly, the DFM rule checking function effectively improves product yield and reduces production costs by optimizing the design to adapt to the manufacturing process. It takes into account multiple aspects, from material selection to stacking structure, from geometric rules to test feasibility, to ensure that the design is not only feasible in theory, but also has high efficiency and high yield in actual production. This comprehensive checking function not only improves product quality, but also enhances the competitiveness of enterprises in the market. With the increasing complexity and miniaturization of electronic products, the importance of DFM rule checking in the electronic design process will only become more and more prominent.

[0070] Among them, the main inspection items of DFM rule inspection include: Geometry rule checking: minimum line width and spacing checking, hole diameter and hole spacing verification, copper area and copper balance analysis.

[0071] Manufacturing process related inspections: Etching and plating uniformity analysis, welding and assembly feasibility inspection, inter-layer alignment tolerance verification.

[0072] Test and inspection related checks: test point accessibility analysis, optical and X-ray inspection compatibility checks.

[0073] Material and structure related checks: stack-up structure optimization suggestions, material compatibility verification, thermal expansion matching analysis.

[0074] Special process related checks: FPC specific rule checks, high density interconnect (HDI) design rule verification, buried via and microvia structure analysis.

[0075] As an embodiment, check whether the conductors are too close to each other at the inner edge of the board frame (including the slot edge), set the minimum spacing parameters for the inner layer and the surface layer respectively, and check for errors.

[0076] Statistical report checks enable multi-dimensional statistical analysis. The statistical report function is a powerful analysis tool that provides comprehensive data analysis and visualization capabilities to help design teams gain insight into design quality, identify problem patterns, and make data-driven decisions. The statistical report function provides a multi-dimensional analysis perspective, allowing design teams to evaluate the quality and performance of designs from different angles. These reports are not just simple lists of data, but a set of complex analysis tools that can reveal deep-seated design patterns and potential problems.

[0077] The statistical report check can check the following reports.

[0078] Performance analysis report: The performance analysis report comprehensively evaluates the overall quality and efficiency of the design. Including: Design completion index: Displays the degree of completion of each aspect of the design. Rule compliance rate: Statistical proportion of compliance with various design rules. Iteration efficiency analysis: Tracks the efficiency of design modification and displays the number of problems solved in each iteration. Time trend analysis: Displays the trend of design quality over time.

[0079] Defect analysis report: In-depth analysis of problems and defects in the design. Includes: Defect type distribution: Displays the proportion of different types of defects in the form of pie charts or bar charts. Severity classification: Classifies and counts defects according to their severity. Root cause analysis: Attempts to trace the root cause of the defect to help prevent similar problems. Resolution time analysis: Statistics on the average resolution time of different types of defects.

[0080] Defect Density Analysis: This analysis focuses on the distribution of defects in the design. Includes: Heat Map Display: Visually displays areas of high defect density in the design. Density Trend Analysis: Shows how defect density changes as the design progresses. Module Comparison: Compares defect densities of different modules or functional blocks. Density Threshold Alert: Issues an alert when the defect density in a certain area exceeds a preset threshold.

[0081] Design complexity analysis: evaluates the complexity of the design and its impact on quality. Includes: Component density analysis: evaluates the number of components per unit area. Interconnection complexity: analyzes the complexity of signal lines. Layer utilization: evaluates the utilization of each layer in a multi-layer design. Complexity and defect correlation analysis: studies the correlation between design complexity and defect occurrence.

[0082] Comparative analysis reports: These reports allow comparisons across different dimensions. For example: Version comparison: Compare design improvements between versions. Project comparison: Compare design quality across projects to identify best practices. Team performance comparison: Analyze the performance of different design teams. Technology platform comparison: Compare design performance across different technology platforms or processes.

[0083] Custom reports and dashboards: Allow users to create custom reports based on specific needs. Includes: Configurable KPI (Key Performance Indicator) tracking. Interactive data visualization tools. Report template customization and sharing capabilities.

[0084] These multi-dimensional statistical reports not only provide in-depth insights into the current design status, but also help the team predict and prevent potential problems. Through these data-driven analyses, design teams can continuously optimize their processes, improve design quality, reduce rework, and ultimately speed up time to market and improve product reliability. In addition, these reports support data export and integration with other enterprise systems, allowing design data to be seamlessly connected to a wider range of product lifecycle management (PLM) and enterprise resource planning (ERP) systems, providing strong support for decision-making across the entire organization.

[0085] In some embodiments, the configuration of the design rules includes: Obtain a rule grouping template in a knowledge base, wherein each grouping includes more than one inspection item; Add target basic rules to the rule grouping template and store them in the rule group, and set corresponding parameters for each rule group; Store all rule groups into the rule base.

[0086] Among them, all rule group templates stored in the server can include the same or different inspection items in each group, and the parameters of the same inspection item in different groups can also be different. All inspection items in the server can be added using the interface we provide.

[0087] Specifically, Figure 3 As shown in the figure, for the configuration of design rules, administrators can create and maintain a set of standardized DRC rule configurations that can be uniformly applied across the organization to ensure consistency. The rule set can be customized according to specific projects, process nodes, or customer requirements, supporting the creation and modification of complex rules such as conditional rules or parameterized rules.

[0088] In some embodiments, it also includes: Make changes to the design rules.

[0089] The modification of the design rules includes at least one of the following: modifying or configuring the design rules according to standard rules; Configure or change design rules based on target project, process node, or target requirements; Roll back the design version to any historical version based on the design rules.

[0090] The configuration files in this application can be version controlled to track the change history of the rules, making it easy to roll back to the previous configuration version or compare the differences between different versions.

[0091] This application provides a design rule checking method for PCB design. Administrators can set different levels of access rights to control who can view, edit or apply rules. When process rules or company standards change, administrators only need to update the configuration in one place, and the updated rules can be automatically applied to all related projects without modifying them one by one. Rule templates and libraries can also be created and quickly applied to new projects, which helps to establish best practices and improve the consistency of design quality. This application can also parameterize the configuration, allowing rules to be adjusted by parameters to adapt to different design requirements without rewriting the rules. Centralized configuration management helps capture and share design knowledge within the organization, and new employees can quickly understand and apply the company's design standards.

[0092] The configurability of design rules in this application reflects the flexibility and adaptability of the system. The mechanism uniformly configured by the administrator ensures the consistency and controllability of inspection standards throughout the organization. Achieve centralized management: Administrators can quickly adjust inspection standards based on different projects, product lines or customer needs to ensure that all designers use the latest and most relevant rules. Rule library version control: Different versions of the rule library can be maintained to facilitate tracking of rule change history, and can be traced back to previous versions when necessary. Custom rule creation: In addition to standard rules, the system also supports the creation of custom rules specific to a company or project. Rule parameterization: Allows parameters to be set for rules so that the same rule can be applied to different design requirements. Rule inheritance and iteration: A basic rule library can be set up, and then local adjustments can be made for specific projects, which ensures consistency and provides flexibility. Based on permission management, the rule library knowledge base can be iteratively upgraded.

[0093] The automated checking function integrated into the design software by this application greatly improves efficiency and accuracy. The advantages of this feature include: Real-time checking: supports real-time or quasi-real-time rule checking during the design process, helping designers to find and correct problems in a timely manner. Comprehensive data acquisition: Direct access to design data instead of relying on exported Gerber files makes the inspection more comprehensive and accurate. Batch inspection capabilities: Batch inspections can be performed on multiple design files or the entire project at the same time to improve work efficiency. Intelligent rule application: The system can automatically select the applicable rule library based on the specific characteristics of the design (such as the number of layers, density, etc.). Customization of inspection items: Designers can choose to run only specific inspection items to quickly verify certain specific aspects. Classification and prioritization of inspection results: Automatically classify the problems found by severity or type to help designers prioritize key issues. Online review tools: The problems of inefficiency and high communication costs of traditional review processes are solved through online review tools.

[0094] This application can also achieve positioning, and the ability to check and modify directly in the design environment greatly improves work efficiency. Interactive error viewing: Designers can highlight problem areas directly in the design view to facilitate quick understanding and location of problems. Context-sensitive repair: The system can provide intelligent repairs based on detected problems, and even automatically repair simple errors. History tracking: Records the history of each modification to facilitate backtracking and understanding of the design evolution process. In general, these features of the DRC system not only improve design quality and efficiency, but also enhance team collaboration and knowledge management. This integrated, automated and intelligent solution provides users with a significant competitive advantage.
