Layer Assignment for Crosstalk Risk Minimization Conference Paper uri icon

abstract

  • In ultra-deep submicron technology, crosstalk noise is so severe that crosstalk avoidance merely in detailed routing is not adequate and it has to be considered in earlier design stages. In this paper, we propose two heuristics for crosstalk mitigation in layer assignment, which is a stage between global routing and detailed routing, so that subsequent crosstalk avoidance in detailed routing can be more attainable. The pre-detailed-routing crosstalk is estimated through a probabilistic model. The constraint on the amount of vias is also considered. Experimental results on benchmark circuits confirm the effectiveness of the proposed heuristics.
