Abstract: This paper introduces a novel algorithm for delay extraction-based passive macromodeling of multiconductor 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 macromodel for SPICE simulation. The new method leads to compact, low-order macromodels resulting in faster transient simulations.

Spectrally Accurate Causality Enforcement using SVD-based Fourier Continuations for High Speed Digital Interconnects
TL;DR: In this article, an accurate and robust technique for accessing causality of network transfer functions given in the form of bandlimited discrete frequency responses is presented. But the method is limited to detecting very small localized causality violations with amplitudes close to the machine precision.
