PROBLEM TO BE SOLVED: To design an integrated circuit which surely satisfies a design rule and also to shorten the time required for verifying whether a relevant rule is satisfied. SOLUTION: In the system where a design s checked about an integrated circuit consisting of plural cells, a prescribed distance is set between each of input/output cells 2 arranged around a cell area 1 and other input/output cells. Since this set distance differs according to the wiring materials, a space is secured by a distance corresponding to the wiring material that requires the longest distance. In other words, the cell space is decided in response to the minimum wiring space corresponding to the wiring material that is decided by a design rule. It is verified whether the integrated circuit that is produced according to the decided cell space is accordant with the design rule. Thus, the time required for verification is shortened since verification can be omitted about combinations with other cells.
