Abstract
A method and a system is described to predict effects of coupling on timing by estimating the delta delay and delta slack that can occur due to coupling on any net, for optimization to minimize the sensitivity of slack to potential coupling violations. The invention protects against other unexpected increases in effective load capacitance, such as those due to unexpectedly long wire routes. It also estimates the delay impact of a single 'fault' or 'event', such as a coupling event or unexpectedly long wires routes, including the impact of slew propagation.
