Front-stage FFs 31-36, a rear-stage FF37, and the logical circuit surrounded with them are extracted firstly from the design information and encoded in easy-to-handle format by subsequent processing. Then, the timing difference between the front-stage FFs 31-36 and rear- stage FF37 is calculated. Then, the delay time of all logical paths of the logical circuit surrounded with the front-stage FF groups 31-36 and rear-stage FF group 37 is calculated. The delay time of each logical path is compared with the timing difference, and the processing is completed when the delay time of all the logical paths is smaller than the timing difference. The gate of a logical path which exceeds the timing difference is substituted with a gate having a fast operation speed.
