Abstract :
This paper presents strategies to insert buffers in a circuit, combined with gate sizing, to achieve better power-delay and area-delay tradeoffs. The delay model incorporates placement-based information and the effect of input slew rates on gate delays. The results obtained by using the new method are significantly better than the results given by merely using a TILOS-like transistor sizing algorithm alone
