System and method for analyzing response values sum of differential signals

摘要

A method for analyzing response values sum of differential signals includes: receiving configurations of simulation parameters; simulating differential signal paths with an analog transmission channel according to a design file; analyzing the analog transmission channel into different channel modes according to received configurations; simulating a plurality of pulse signals into the analog transmission channel according to the received configurations, and recording an impulse response of each of the channel modes; simulating differential signal transmissions of the differential signals according to the received configurations, and analyzing the differential signal transmissions into different signal modes corresponding to the different channel modes; transforming each signal mode and the impulse response of a corresponding channel mode to respectively generate a first value and a second value by utilizing Fast Fourier Transform Algorithm; multiplying the first value by the second value to generate a third value, and transforming the third value to a fourth value by utilizing an Inverse Fast Fourier Transform Algorithm; and summing all the fourth values corresponding to all of the channel modes to be the response values sum of the differential signals.
