Abstract :
We analyze the impact of wiresizing on the performance of Elmore-based routing constructions. Whereas previous wiresizing schemes are static (i.e., they wiresize an existing topology), we introduce a new dynamic wiresizing technique, which uses wiresizing considerations to drive the routing construction itself. Simulations show that dynamic wiresizing affords superior performance over static wiresizing, and also avoids topological degeneracies. Moreover, dynamically-wiresized Elmore-based routing constructions significantly outperform all previous methods (including A-Trees) in term of maximum source-sink signal delay, affording to 73% average SPICE delay improvement over traditional Steiner routing
