A fast and precise eye-diagram estimation method for a channel of a pair of differential microstrip lines on PCB with arbitrary terminations

Abstract

In this paper, we propose a fast and precise eye-diagram estimation method for a channel of a pair of differential microstrip lines on PCBs with arbitrary source and load terminations. The voltage transfer function of a channel is investigated as a quick measure of the signal integrity of a channel and the DDJ and eye-opening voltage values are precisely estimated by using a modified peak distortion analysis. The efficiency and the accuracy of the proposed eye-diagram estimation method were successfully verified through HSPICE simulations.
