A multiline model for time-efficient estimation of crosstalk

Abstract

This work proposes a novel and accurate crosstalk noise estimation method in the presence of multiple RC lines for use in design automation tools. Using the realistic exponential waveform and a reduced transfer function, the proposed model presents a complete multiline noise model by representing active and passive aggressors simultaneously on the victim line. In the model, active aggressors are easily represented by current sources and passive aggressors are accurately modeled as equivalent capacitances to victim. Each current source representing an active aggressor carries the same accuracy as the 2-π representation. Equivalent capacitances for passive aggressors, on the other hand, consider resistive shielding effect and the realistic exponential aggressor waveform. This approach allows one to obtain a general noise model that considers the effect of many active and passive aggressors and general formulas derived can easily be applied to real cases. Noise peak and width expressions are derived and results are in good agreement with HSPICE results. Results show that average error for noise peak is 4.3% and for the width is 6.9% while allowing for very fast analysis.
