PROBLEM TO BE SOLVED: To complete detailed wiring intended by a layout designer in a short time in wiring path setting of a semiconductor integrated circuit. SOLUTION: A floor plan and such grid lines that covers the floor plan are displayed after deciding the floor plan of a semiconductor integrated circuit chip, and when unit coordinate areas (grid area) surrounded with adjacent grid lines where an inter-block net being an object passes through and their sequences are instructed, the coordinates values and passing sequences of the grid areas are set as a rough wiring path. Next, automatic detailed wiring is performed under a condition that the object inter-block net passes through the rough wiring path which has been set after deciding detailed arrangement of a gate.
