PROBLEM TO BE SOLVED: To shorten the operation time when executing the layout design of an upper layer power supply wiring to the layout of a lower layer power supply wiring in an automated designing of the layout of an integrated circuit IC such as a large-scale integrated circuit LSI, and also to prevent such a situation that operation becomes impossible. SOLUTION: This integrated circuit design device comprises a layout design means for executing the automatic design of the layout of the integrated circuit. The layout design means comprises a layout simple designing means for simplifying, when executing the automatic design of layout of the upper layer power supply wiring to the layout of the lower layer power supply wiring, the layout of the lower layer power supply wiring, and executing the automatic design of the layout of the upper layer power supply wiring to the simplified layout of the lower layer power supply wiring, thereby automatically designing the layout of the upper layer power supply wiring to the original layout of the lower layer power supply wiring.
