摘要

PROBLEM TO BE SOLVED: To simplify SI simulator input work when performing an SI analysis on the whole signal extending over a plurality of components and a plurality of circuit boards.SOLUTION: Provided is a circuit board trial manufacture pre-verification system having a signal quality analysis function for analyzing the waveform and delay time of each signal on a signal path that is designated, the circuit board trial manufacture pre-verification system comprising: start point/end point acceptance means for accepting the designation of a start point and an end point of a signal passing through a plurality of components and/or a plurality of circuit boards; signal path collection means for identifying a signal connected to the start point on the basis, as for "in a circuit board," of circuit diagram information indicating correspondence between a component pin and a signal and component information indicating the relationship of connections of a plurality of pins of a component, and on the basis, as for "between circuit boards," of connector wiring information indicating the correspondence of connection pins, and repeating a process for sequentially tracing signals until the end point is reached or no connection destination exists; and output means for outputting, for the signal quality analysis function, a list of signals present on the signal path from the start point to the end point as acquired by the signal path collection means.
