METHOD FOR DESIGNING SEMICONDUCTOR DEVICE, PROGRAM, AND DESIGN DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress the occurrence of jitter constraint violation.SOLUTION: A method of designing a semiconductor device comprises the steps of: obtaining a relation between a distance from a back bias control unit 1 that controls the back bias of a transistor Tr and the amount of noise of a control signal that is output from the back bias control unit 1 (step S1); obtaining the amount of increase in jitter due to the amount of the noise on a clock path that is connected to a circuit section (IP macro) 2, on the basis of a relation between the back bias control unit 1 and the amount of noise (step S2); and arranging the circuit section 2 and clock path on the basis of the amount of increase in the jitter and an allowable value of the jitter in the circuit section 2 (step S3).
