Embodiment 1
[0039] Such as figure 1 As shown, a design method for classifying and displaying DRC in PCB design includes the following steps:
[0040] S1. Obtain the layer information included in the current design, add it to the DRC Layer menu in the pop-up window, obtain the DRC type included in the current design, and add it to the DRC Type menu in the pop-up window after processing;
[0041] S2. Build an update function to update the DRC Type menu list according to the user input action;
[0042] S3, obtaining each item attribute in the DRC Layer menu list and the DRC Type menu list, inserting into the updated DRC Layer menu list and the DRC Type menu list to form a feature parameter list;
[0043] S4. Matching the object selected in the DRC list with the DRC in the current design is realized by means of coordinate and level feature matching.
Embodiment 2
[0045] Such as figure 2 As shown, a design method for classifying and displaying DRC in PCB design includes the following steps:
[0046] S1. Build a pop-up window and add controls;
[0047] S2. Obtain the layer information included in the current design, add it to the DRC Layer menu in the pop-up window, obtain the DRC type included in the current design, and add it to the DRC Type menu in the pop-up window after processing;
[0048] S3. Monitor the status of the controls in the pop-up window, and obtain the user's actions;
[0049] S4, build an update function, update the DRC Type menu list according to the user input action;
[0050] S5. Obtain each item attribute in the DRC Layer menu list and the DRC Type menu list, and insert them into the updated DRC Layer menu list and DRC Type menu list to form a feature parameter list;

Abstract
The invention discloses a designing method for DRC classification displaying in PCB designing. The designing method includes the following steps of obtaining layer information included by current design, adding the layer information into a DRC Layer menu in a pop-up window, obtaining a DRC type included in the current design, processing the DRC type, and then adding the processed DRC type into a DRC Type menu in the pop-up window; establishing an updating function, and updating a DRC Type menu list according to a user input action; obtaining all item attributes in the DRC Layer menu list and the DRC Type menu list, and inserting the item attributes into the updated DRC Layer menu list and the DRC Type menu list to form a characteristic parameter list; matching objects selected in the DRC lists with DRC in the current design in a coordinate and layer characteristic matching mode. DRC classification displaying including type classification and layer classification of the DRC is achieved, the two kinds of classification can be simultaneously conducted, single classification can also be conducted, working efficiency is greatly improved, unmodified bugs of the important DRC are avoided to a certain degree, and design quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of PCB, in particular to a design and operation method for classifying and displaying DRC in PCB design. Background technique [0002] There are many kinds of PCB design software on the market. Cadence is the most widely used software in the industry, not only because it has powerful functions and a variety of related software as support, but also because it provides an open secondary development interface and relatively complete The development language library, users can develop according to their own needs. The skill language is a high-level programming language based on C language and LISP language built into the Cadence software. Cadence provides a wealth of interactive functions for the skill language. Researching the skill language and then writing tools can greatly improve work efficiency. [0003] In the later stage of PCB design, engineers need to view and modify DRC one by one. DRC refers to Desi...
