Abstract
In this paper, we consider the problem of selecting a set of aggressor nets that maximize crosstalk induced noise or delay pushout on a coupled victim net, under given logical constraints. We formulate the problem mathematically, and propose efficient Lagrangian Relaxation and network flow based approaches that guarantee an optimal solution. We also formulate and solve this problem while considering the noise susceptibility of the victimpsilas receiving gate. Experimental results show that the proposed approaches are run-time efficient by factors of up to 800times in comparison to an exhaustive search approach, and reduce timing pessimism by up to 36%.
