Crosstalk analysis of simultaneously switching interconnects

This article focusses on the waveform analysis and crosstalk peak estimation at far-end of victim line for simultaneously switching inputs with resistive drivers. A low loss coupled transmission line-model of interconnect is used for analytical purpose. Noise peaks are estimated for the conditions when inputs to two coupled interconnects are switching in-phase and out-of-phase. Waveforms are analysed in general with homogeneous and non-homogeneous drivers for unipolar inputs. The driver is modelled as linear resistance. Comparison of the analytical results with simulation programme with integrated circuit emphasis (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, their timings and waveform shape for all switching conditions with an average error of less than 4%.
