For upcoming industrial specification of very high speed signals, channel discontinuity and crosstalk become important.
Channel based methods are ready for signal integrity evaluation of complex signal transmission mechanism.
A quick solver with sufficient accuracy is necessary for detail channel effect modeling of very high speed signals.
As channel discontinuity and crosstalk dominating, accuracy of channel based methods would be critical issue.
Though, channel based methods couldn’t take interaction between chip buffer and channel into account.
