Traveling-wave-based waveform approximation technique (TWA) for efficient signal integrity verification of strongly coupled VLSI interconnect lines

Abstract

a traveling-wave-based waveform approximation (TWA) technique is presented. The technique can be efficiently as well as accurately applied for the signal integrity verification of inductance-effectprominent multi-coupled RLC transmission lines. The method suggests that a steady-state traveling wave is approximately determined by a three-pole approximation in frequency domain. Then the time-domain response of the system is determined by using the traveling waves that are modeled by multiple reflections. It is shown that the TWA-based signal transients have excellent agreement with HSPICE simulation.
