System and method for verifying trace distances of a pcb layout

Abstract

A system for verifying trace distances of a PCB layout includes a computer () and a database (). The computer includes: a segment receiving module () for receiving segments of a selected trace, and depositing the segments in a segment set; a segment selecting module () for selecting an unverified segment from the segment set; a distance setting module () for setting a searching distance; an area ascertaining module () for ascertaining a rectangular area; a segment searching module () for searching segments of other traces in the rectangular area; a distance calculating module () for calculating a distance between the unverified segment and each searched segment; a distance comparing module () for comparing the calculated distances to obtain a shortest distance, and comparing the shortest distance with a preset benchmark distance; and a verification determining module () for determining whether all segments of the selected trace has been verified.
