2-π Crosstalk noise model for deep submicron VLSI global RC interconnects

Noise estimation and avoidance are becoming very important issues in today's high performance IC design. This paper presents a much improved, highly accurate and efficient noise model called 2-π model for the estimation of crosstalk noise. The proposed model incorporates all the physical properties including victim and aggressor drivers, distributed RC characteristics of interconnects and coupling locations of both victim and aggressor lines. Then with the help of this model, expressions for peak noise and noise width as well as sensitivity expressions to the various model parameters are calculated. We then use these sensitivity expressions to analyze and evaluate the effectiveness of various noise avoidance techniques for the reduction of this crosstalk noise.
