System and method for verifying trace distances of a PCB layout

摘要

A system for verifying trace distances of a PCB layout includes a computer ( 10 ) and a database ( 11 ). The computer includes: a segment receiving module ( 100 ) for receiving segments of a selected trace, and depositing the segments in a segment set; a segment selecting module ( 101 ) for selecting an unverified segment from the segment set; a distance setting module ( 102 ) for setting a searching distance; an area ascertaining module ( 103 ) for ascertaining a rectangular area; a segment searching module ( 104 ) for searching segments of other traces in the rectangular area; a distance calculating module ( 105 ) for calculating a distance between the unverified segment and each searched segment; a distance comparing module ( 106 ) 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 ( 107 ) for determining whether all segments of the selected trace has been verified.
