PROBLEM TO BE SOLVED: To achieve a high density LSI while properly preventing the minimum metal area error. SOLUTION: An automatic wiring device 10 divides the metal area into rectangles, calculates the area of each divided rectangle, calculates the total area of the rectangles, and then decides whether the metal area thus calculated is smaller than a predetermined threshold, i.e. the minimum metal area. If a decision is made that the metal area is smaller than the minimum metal area, the automatic wiring device 10 corrects the wiring of the LSI so that the metal area becomes equal to or larger than the minimum metal area.
