A simplifiediyansmission-line based crosstalk noise model for on-chip RLC wiring

Abstract

In this paper, we prerent B new RLC emstalk noise model Ihat combines simplicity, accuracy, and generality. The new model b based on transmission line theory and is applicable to asymmetric driver and line conliguratiions. The results show that the model captures both Ihe waveform shape and peak noise accurately (average emr in peak noise was 6.5%). A key feature of the new model is Ihat its derivation and form enables physical insight into Ihe dependency of total coupling noise on Itlevant physical design paramten. The model is applied to investigate Ihe impact of various physical design optimizations (e.g., wire sizing and sparing, shield insertion) on total RLC coupled noise. Results indicate that wmmon (capacitive) noise avoidance techniques can behave quite dilTerenUy when baIh capacitive and inductive coupling are convidered together.
