PROBLEM TO BE SOLVED: To simply modify the layout of wiring in a primitive cell that can modify the layout of wiring by FIB machining. SOLUTION: For example, by a CAD tool, dummy wiring Da to Dd of the uppermost layer is provided at a plurality of cells Ia1, Ib1, Ia2, Ib2, and Ia3 for cell-based design being generated, on the basis of the algorithm of automatic arrangement wiring for short-circuiting over the entire cells Ia1, Ib1, Ia2, Ib2, and Ia3. Then, by the FIB machining, the dummy wiring Da to Dd is connected to each of terminals Za1, Bb1, Ab1, Za3, Zb1, Bb2, Za2, and Ab2 via additional wirings Wa', Wb', Wc', and Wd' with the shortest distance.
