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

A system for checking a length of a wire path between a capacitor and a via of a PCB design, the system comprising a host computer and a database, the database storing length criteria and the PCB design which comprises information on capacitors comprising pins of the capacitors and positions of the capacitors, and information on vias comprising positions of the vias that correspond to the positions of the capacitors, the host computer comprising:

• an obtaining module configured for obtaining length criteria and information on capacitors from the database;
• a selecting module configured for selecting one or more capacitors and pins of selected capacitors from the obtained information on capacitors, and for selecting one of the length criteria;
• the obtaining module further configured for obtaining positions of selected capacitors, and positions of vias corresponding to the positions of selected capacitors from the database;
• a calculating module configured for calculating 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;
• a judging module configured for determining 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
• an output module configured for outputting check results of the judging module.
