Crosstalk timing model for high-speed interconnects with impedance discontinuity

Abstract

In this paper, we propose a simple and efficient model to predict the timing impact of crosstalk in high-speed interconnects with impedance discontinuities. This model is based on the reflection and superposition principles. The results of the simple model are accurate to picoseconds or less, when compared to HSPICE simulations with 1~40mm interconnect length. The model can also be extended to deal with multiple parallel interconnects. In addition, this model can predict timing results relatively quickly, compared to simulation by HSPICE.
