Crosstalk Analysis of Simultaneously Switching Coupled Interconnects Driven by Unipolar Inputs through Heterogeneous Resistive Drivers

Abstract

This paper focuses on waveform analysis and crosstalk peak estimation at far-end of victim line for simultaneously switching inputs with resistive drivers. A transmission line based low loss coupled ALC-model of interconnect is used for analytical purpose. Positive and negative peaks are estimated for the conditions when inputs to two coupled interconnects are switching in-phase and out-of-phase. Waveforms are analyzed in general with homogeneous and non-homogeneous drivers for unipolar inputs. The driver is modeled as linear resistance. Comparison of analytical results with SPICE extracted results shows that the error involved is less than 2% and 5% for in-phase and out-of- phase switching respectively. The comparisons of analytically obtained results with SPICE simulations show that the proposed model captures noise peaks and waveform shape quite well.
