Abstract

The present application discloses a method and system for differential wiring in PCB design. The method includes: using a pair of differential signal lines to generate N differential line pairs to be processed in the current PCB board; using N pairs of the differential line pairs to be processed generating a second thick line; moving the second thick line to a target position; at the target position, taking the center line of the second thick line as a reference, generating N pairs of differential line pairs again. The system includes: a first routing module, a thick line generating module, a moving module and a second routing module. Through the application, the efficiency and accuracy of differential wiring in PCB design can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of PCB (Printed Circuit Board, printed circuit board) design, in particular to a method and system for differential wiring in PCB design. Background technique [0002] In the PCB design and pre-evaluation stage, designers need to pre-evaluate all differential line buses, so as to continuously optimize the PCB design. With the development of high-density boards, PCB boards are becoming more and more refined and miniaturized, and the speed of differential wiring is getting higher and higher, and the requirements for the quality of differential wiring are also getting higher and higher. Therefore, how to carry out differential wiring in PCB design, so as to evaluate PCB design, is an important issue. [0003] At present, the method of differential wiring in PCB design is usually a simple evaluation. First, a thick line is drawn as the evaluation channel, and then each pair of differential signals is ...
