Abstract

The embodiment of the invention discloses a method and system for automatically adding heat dissipation holes in PCB design, and the method specifically comprises the steps: searching an open region on a PCB, and enabling the open region to be one or more closed regions; creating an openable sub-region outline greater than or equal to the original pixel in all the open regions; merging all the sub-region outlines capable of being perforated on the PCB, drawing an upper boundary for the merged outlines, and taking the boundary size of the merged outlines as the perforation size of the perforated region; and performing expanding outwards by 20 mil according to the size of the open pore, and drawing an outer frame for forbidding all layers of wiring, wherein the outer frame is the forbidden area Rout keepout _ all. The method and the system provided by the embodiment of the invention are used for automatically searching all areas capable of being perforated in the PCB; and the outline andthe forbidden area are rapidly added, so that the problems of low aperture ratio and easy omission of the openable points caused by manual search of the openable area and low efficiency caused by manual addition of the openable frame and the forbidden area in the existing scheme are solved.

Description

technical field [0001] The invention relates to the technical field of PCB design, in particular to a method and system for automatically adding heat dissipation openings 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. Cadence not only has powerful functions and a variety of related software as support, but also provides an open secondary development interface and a relatively complete development language. Library, users can carry out secondary development according to their own needs. Skill language is a high-level programming language based on C language and LISP language built into Cadence software. Cadence provides rich interactive functions for skill language. Researching skill language and then writing auxiliary tools for application can greatly improve work efficiency. [0003] In the server system architecture, the heat dissipation of the front backplan...
