Method to quickly estimate inductance for timing models |
摘要 |
A method of estimating an inductance delay includes determining a resistance-capacitance (RC) delay with resistances and capacitances of a network and estimating an inductance delay of the network by determining a propagation delay of an electromagnetic (EM) field across wires of the network. Additionally, the method includes determining if the RC delay is below a specified threshold and adding the estimated inductance delay to the RC delay to determine a total time to propagate voltage swings through the network if the RC delay is below the specified threshold.
