چکیده

The Noise estimation and avoidance are becoming critical, in today’s high performance IC design. An accurate yet efficient crosstalk noise model which contains as many driver/interconnect parameters as possible, is necessary for any sensitivity based noise avoidance approach. In this paper, we present an analysis for crosstalk noise model which incorporates all physical properties including victim and aggressor drivers, distributed RC characteristics of interconnects and coupling locations in both victim and aggressor lines. Also shown that crosstalk can be minimized by driver sizing optimization technique. These models are verified for various deep submicron technologies. KeywordsCoupling; crosstalk; Interconnect; noise; victim.
