METHOD FOR DETERMINING THE CRITICAL PATH OF AN INTEGRATED CIRCUIT

摘要

in order to determine the critical path of a circuit, firstly the paths, the mean path runtimes and the path runtime variations thereof are determined. Paths with similar statistical parameters are collated into path groups. A statistical group figure for each path group and a statistical total figure for all paths considered are than calculated. Finally the critical path is determined by means of a comparison of the group figures at or above a critical path runtime Tc taking into account the total figure.
