Abstract :
The accuracy of interconnect delay estimations can be improved by the method presented in this paper, in which the first two moments are obtained with ABCD matrix and a stable model to incorporate effects of transport delay into the delay estimate is developed. Simulation results show that the method share the same accuracy with traditional methods when rise time delay is much longer than transport delay and more accurate when the two are of the same order.
