A circuit model of a system of VLSI interconnects for time responsecomputation

A novel computational model based on the spectral-domain approach for the characterization of a dispersive multiconductor system is developed for time response computation. The model consists of two identical impedance networks and equivalent voltage-controlled voltage sources, and it is particularly suitable for timing analysis. Since the model is constructed based on full-wave analysis, the hybrid nature of the VLSI interconnects is taken care of, and thus the model is valid at high frequencies when the longitudinal field components are no longer negligible. Signal distortions due to the dispersive nature of a multiconductor system are demonstrated by an example
