System and method for checking a length of a wire path between a capacitor and a via of a PCB design

摘要

A method for checking a length of a wire path between a capacitor and a via of the PCB design obtains length criteria and information on capacitors from a database, selects one or more capacitors and pins of the selected capacitors from the obtained information on capacitors and selects one of the length criteria, and obtains positions of selected capacitors and positions of vias corresponding to the positions of selected capacitors from the database. The method further calculates each length of a wire path between a selected capacitor and a corresponding via according to the position of the capacitor and the position of the via, determines whether each calculated length of a wire path between a selected capacitor and a corresponding via is acceptable according to a comparison with the selected length criterion, and outputs check results of the determining step.
