Eye diagram estimation and equalizer design method for PAM4

The extended peak distortion analysis (ePDA) is proposed in this paper for the eye diagram estimation of high speed interconnects in PAM4. The method can construct the eye diagram much faster than by PRBS eye simulation. In addition, the genetic algorithm is established to find the optimal tap numbers and coefficients of the feed-forward equalizer (FFE) so as to minimize the inter-symbol interference (ISI) effectively and efficiently.
