Abstract
The disclosure is a technique to describe a complex coupled multi-port transmission line system in terms of a time-domain Green's function and then implement this description into a circuit simulator. This permits highly accurate simulation of arbitrary transmission line networks with non-linear transistor level models of digital devices and avoids reliance on non-physical approximations of the behavior of the transmission line or digital device termination. The method is particularly applicable to digital systems which experience transmission line effects of printed circuit board tracks.
