PROBLEM TO BE SOLVED: To eliminate a hold error competing with a set-up error in an RC worst corner. SOLUTION: A timing analysis result analyzed by using a corner condition maximizing a time constant of a design object circuit is acquired. Thereafter, a clock net, within a clock tree related to the design object circuit, generating a hold error competing with a set-up error is detected based on the timing analysis result, and the wiring width of wiring in the clock net is changed to a wiring width larger than that of other wiring different from the wiring.
