An efficient eye diagram generation method for jitter analysis in high speed links

Abstract

This paper proposes a novel and efficient jitter analysis method for high speed links. Based on step responses of the high speed link and information of jitters injected, the proposed method generates the eye diagram of link receiver for jitter impact evaluation. In this method, the range of jitter is converted into the range of voltage variation on step responses. Bounds of the eye diagram are calculated through the ultimate value of voltage variation on step responses, which dramatically improves the calculation efficiency with high accuracy. Another advantage of the proposed method is that the jitter is processed in time sequence. It helps the proposed method analyze the time correlated jitter correctly.
