Delay extraction-based passive macromodeling techniques for transmission line type interconnects characterized by tabulated multiport data

摘要

This paper introduces a novel algorithm for delay extraction-based passive macromodeling of multi-conductor transmission line type interconnects characterized by multiport (Y, Z, S, or H) tabulated parameters. The algorithm determines a unique logarithm of the H parameters, which is then approximated using a low-order rational function. Subsequently, the DEPACT (delay extraction-based passive compact transmission line macromodel) algorithm is applied to obtain a passive and causal macro-model for SPICE simulation. The new method leads to compact, low-order macromodels resulting in faster transient simulations.
