Abstract
A system for verifying signal propagation delays of circuit traces of a printed circuit board (PCB) layout includes a computer (). The computer includes: a setting module () for setting a minimum propagation delay and a maximum propagation delay for a trace to be verified, and making a selection regarding whether to calculate a propagation delay of a lead wire connected with the trace; a selecting module () for selecting a segment from a segment set of the trace; a calculating module () for calculating a propagation delay of the segment, the trace and the lead wire, and a total propagation delay; and a determining module () for determining whether all segments of the trace have been calculated, and whether the total propagation delay is between the minimum propagation delay and the maximum propagation delay. A related method is also disclosed.
