Elmore delay estimation of two adjacent coupling interconnects

摘要

An approach to analyze coupling RC interconnect delay based on "effective capacitance" is presented in this paper. We compare this new method with the traditional method that uses Miller capacitance. Results show that it not only improves the accuracy but also reflects the delay dependence on rise time. The method has the same complexity as the Elmore delay and can be widely used in performance-driven routing optimization.
