PROBLEM TO BE SOLVED: To provide a design method for an integrated circuit capable of more optimizing the performance of the integrated circuit. SOLUTION: After an initial layout (S20) is performed, an integrated circuit evaluation step S30, an altered cell selection step S40, and a cell performance alteration step S50 are performed repeatedly. In the altered cell selection step S40, based on the results of the evaluation by the step S30, a cell for altering the performance is selected from the cells forming the integrated circuit. In the cell performance altering step S50, the performance characteristics of the cell selected by the step S40 are determined by referring to a library 15 and using the external conditions thereof.
