Problems solved by technology

[0004] (1) It takes a long time. In large-scale PCB boards, especially large-scale server motherboards, there are many types of differential lines, so manual winding of coupons is slow and inefficient;
[0005] (2) Manual winding makes the coupon height uneven, not accurate enough

Abstract

The present invention relates to the technical field of PCB design, and provides a method and system for generating coupons for testing high-speed signal impedance. The method includes: according to the obtained basic parameters corresponding to differential signal lines that require impedance control, generate impedance control. Any differential signal line A in the differential signal lines; according to the generated differential signal line A, generate another differential signal line B of the differential signal line that needs impedance control; according to the generated differential signal line A and The differential signal line B is converted into a differential line with line width attributes, so as to quickly and accurately draw coupons for impedance control testing, which greatly improves the efficiency of layout engineers designing coupons, solves the time-consuming and inaccurate defects of coupon design, and further improves Improve the quality of PCB high-speed line impedance control.

Description

technical field [0001] The invention belongs to the technical field of PCB design, in particular to a coupon generation method and system for testing high-speed signal impedance. Background technique [0002] At present, there are many kinds of PCB design software on the market. As the most widely used software in the industry, Cadence not only has powerful functions and a variety of related software as support, but also because it provides an open secondary development interface and relatively With a complete development language library, users can develop according to their own needs. Skill language is a high-level programming language based on C language and LISP language built into Cadence software. Skill language can be used not only as the simplest language tool, but also as a powerful programming language for developing any application. Skill can interact with the underlying system and provides a rich interface for accessing various tools of Cadence. Users can acces...
