Abstract
A method and computer program product for finding timing critical nets in an integrated circuit design includes steps of: (a) receiving an integrated circuit design as input; (b) calculating an approximate delay for each net in the integrated circuit design wherein the approximate delay includes an estimate of crosstalk delay; (c) identifying timing critical nets from the calculated delay for each net in the integrated circuit design; (d) calculating a corresponding exact delay for each of the timing critical nets; (e) replacing the approximate delay calculated for each of the timing critical nets with the corresponding exact delay to generate a corrected set of net delays for the integrated circuit design; and (f) generating as output the corrected set of net delays for the integrated circuit design.
