Patent ID: 7398504

Claim:
A computer-readable medium storing a program for analyzing a transmission signal, wherein said program allows a computer to execute: designating a wiring model including a sending end and a receiving end for signal analysis from a design information of a circuit board; analyzing comprising analyzing and generating first output waveforms received at the receiving end when a signal pattern varying from 0 to 1 is input to the sending end, and analyzing and generating second output waveforms received at said receiving end when a signal pattern varying from 1 to 0 is input to said sending end; output waveform generating comprising selecting said first and second waveforms depending on the bits of a random signal of a predetermined bit count and generating, for the predetermined bit count, said first and second output waveforms selected with each bit position as a starting point; and waveform synthesizing comprising synthesizing the output waveforms for the predetermined bit count to generate output waveforms received at the receiving end when the random signal is input to the sending end.
