Layer assignment algorithm for RLC crosstalk minimization

With advances in VLSI technology, crosstalk is becoming a vital factor in high performance designs, making noise mitigation in early design stages necessary. In this paper, we propose a layer assignment algorithm optimizing congestion and crosstalk. A new model for crosstalk noise measuring is developed where wirelength is used as a scale for the potential noise immunity, and both capacitive and inductive coupling between sensitive nets are considered. We also take shield insertion into account for further crosstalk mitigation. Experimental results show that our approach could efficiently reduce maximum noise voltage and the number of shields needed compared to the algorithm proposed by Y. Zhou, et al. (see inbid.,2003).
