Problems solved by technology

In the prior art, the route keep out is generally created manually. For large-scale PCB boards, especially large-scale server main boards, the number of differential pairs is large, manual processing is slow, and the production efficiency of avoiding routing areas is too low; and the shape of manual processing ( Such as circle, ellipse, irregular rectangle, etc.) cannot match the shape of the differential pair PAD, the accuracy is low, and the quality of the differential signal is affected

Abstract

The embodiment of the present invention discloses a method, device, equipment and computer-readable storage medium for generating an avoidance routing area of ​​a differential pair pad. Wherein, the method includes expanding the two pad shapes of the differential pair pins in the circumferential direction according to the expansion distance to form the first path and the second path; points, connect these four points in the same direction to form the third path; delete the intersection of the third path and the first path, the third path and the second path to form the fourth path; generate a differential pair according to the category of the differential pair pins For the area avoiding the routing of the pad, the shape of this area is the same as that of the fourth path. This application realizes fast and accurate positioning of PAD avoiding routing areas, makes up for the defects of low manual processing efficiency, low precision, and inconsistent shapes, effectively shortens the PCB design cycle, improves PCB design efficiency, and improves the differential signal. Transmission quality, thus ensuring the quality of PCB design.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of printed circuit board design, and in particular, relate to a method, device, device, and computer-readable storage medium for generating an avoidance routing area of ​​a differential pair pad. Background technique [0002] With the development of printing technology, users have higher and higher quality requirements for PCB (Printed Circuit Board, printed circuit board), and there are more and more corresponding PCB design software. 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 a relatively complete development language library, users can develop according to their own needs. [0003] Skill language is a high-level programming language based on C language and LISP language built into Cadence software. Skill lan...
