Efficient Delay Calculation in Presence of Crosstalk

Efficient and accurate delay calculation is very important in physical design, optimization and fast verification. In this paper we consider explicit delay calculation for RC interconnects with coupling capacitance.The formulae are derived using a simplified transfer function, which offers enough accuracy. We have expressed coefficients of two-pole transfer function in terms of circuit parameters. Moment matching methods [8][12][13] do not yield such explicit expressions. Our simplified delay calculation method is most suitable in physical design and fast timing verification where the dependency of delay on circuit parameters is essential.
