Fast and accurate bit probability density function (PDF)-based eye diagram estimation method for high-speed systems

Abstract

We first propose an eye diagram estimation method for high-speed systems. An eye diagram shows channel performances in terms of signal integrity (SI)

the has a critical problem that the eye diagram requires a long acquisition time to obtain the accurate result. In order to analyze and reflect the encoding on the eye diagram in the proposed method, the proposed method is based on the bit probability density function (PDF). The proposed method also includes the signal processing block to consider equalizers included in most of high-speed systems. The proposed method is verified by comparing to the transient simulation in the bit error rate (BER). Compared to the previous works, the proposed method first considers the encodings and equalizers included in the high-speed systems.
