Abstract :
This paper presents a fast simulation method for long coupled multi-chip interconnects. The channel is represented through a time-domain passive delay-rational macromodel, which is identified from tabulated scattering samples. A two-level Waveform Relaxation (WR) framework is then applied in order to perform fast transient simulation of the terminated channel via an iterative process. A new over-relaxation scheme is introduced for improving the convergence of the WR iterations.
