Abstract
An extraction tool for, and method of, determining a stage delay associated with an integrated circuit (IC) interconnect. In one embodiment, the extraction tool includes: (1) a driver strength estimator configured to extract dimensions of a driver associated with the interconnect and estimate a driver strength therefrom, (2) a driver delay estimator coupled to the driver strength estimator and configured to estimate a driver delay based on the driver strength, (3) an interconnect delay estimator configured to estimate an interconnect delay based on extracted C and RC parameters associated with the interconnect and (4) a stage delay estimator coupled to the driver delay estimator and the interconnect delay estimator and configured to estimate the stage delay based on the driver delay and the interconnect delay.
