METHOD FOR ADJUSTING DELAY IN SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To quickly perform such delay adjustment in which a delay value does not shift even though fluctuations of temperature and voltage at operation and process dispersion at manufacturing occur concerning a path provided with the complete delay values when designed on a circuit of a semiconductor device. SOLUTION: A delay adjusting method is provided separately with a gate delay adjustment process S2 and a wiring delay adjustment process S3, individually adjusts gate delay and wiring delay, is provided with a gate delay shift allowable quantity calculation process S5 and a wiring delay shift allowable quantity calculation process S7, calculates delay shift allowable quantity in each path to perform necessary minimum delay adjustment and thereby, quickly adjusts path delay including balance between gate delay and wiring delay.
