In this paper, we explore the concept of using analytical models to efficiently generate delay change curves (DCCs) that can then be used to characterize the impact of noise on any victim/aggressor configuration. Such an approach captures important noise considerations such as the possibility of delay change even when the switching windows of neighboring gates do not overlap. The technique is model-independent, which we demonstrate by using several crosstalk noise models to obtain results. Furthermore, we extend an existing noise model to more accurately handle multiple aggressors in the timing analysis framework. DCC results from the analytical approach closely match those from time-consuming SPICE simulations, making timing analysis using DCCs efficient as well as accurate.

~ 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 e m r 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.
