Abstract:

Along with the high speed signaling system data rate rise sharply,regard worst case eye as guidelines will lead to excessive design.Aiming at this phenomenon,this paper puts forward a method of BER to guide the design.We add probability to the pattern,convolve the probability and then arrived at a BER eye.This eye can not only show all the eye but also show the probability of every eye diagram.Simulation results show the effectiveness of the algorithm which achieves fast,efficient and accurate calculation of the eye diagram and its probability of the system.

Key words: jitter, noise, BER eye diagram
