A novel and efficient timing-driven global router for standard cell layout design based on critical network concept

As the CMOS technology enters the very deep submicron era, inter-wire coupling capacitance becomes the dominant part of load capacitance. The coupling effects have brought new challenges to routing algorithms on both delay estimation and optimization. In this paper, we propose a timing-driven global routing algorithm with consideration of coupling effects. The two-phase algorithm based on timing-relax method includes a heuristic Steiner tree algorithm and an optimization algorithm. Experimental results are given to demonstrate the efficiency and accuracy of the algorithm.
