Method and system for automatically checking circuit layout of printed circuit board

Abstract

Method and system for automatically checking a circuit layout of a PCB are disclosed. The method includes acquiring routing constraint information in an automatic table format, converting the routing constraint information from the automatic table format into a readable table format and generating routing constraint information in the readable table format, inputting the routing constraint information in the readable table format into a PCB layout software in a plug-in manner for the PCB layout software to acquire a corresponding circuit routing rule, acquiring, after routing ends, a data file outputted by the PCB layout software, and generating a check report by comparing and checking the data file and the routing constraint information. With the method, the constraint information is automatically inputted into the PCB layout software, and a check report is automatically generated for correcting errors on a circuit layout in the layout software, to improve circuit layout efficiency.
