PROBLEM TO BE SOLVED: To provide an automatic wiring method for a semiconductor integrated circuit which does not cause a phase difference up to a terminal cell without inserting a buffer cell. SOLUTION: In the semiconductor integrated circuit, wiring patterns different in wiring length, wiring width, and wiring material quality are combined, concerning a plurality of wiring patterns prepared in advance, prior to wiring so that the resistance values of the wiring from a clock driver cell to the above terminal cell may be roughly the same, when supplying a plurality of terminal cells with clock signals from the above clock driver cell.
