This <a href="http://literature.cdn.keysight.com/litweb/pdf/5992-1320EN.pdf?id=2694601" target="_blank">DesignCon paper </a>discusses PAM-4 signaling and a new measurement and simulation eco-system. Simulation of PAM-4 signals are done with an IBIS-AMI signal generator, an S-parameter channel model,and remote access software for receiver data recovery. Measured data is from commercially available equipment with specialized waveform processing.
