PROBLEM TO BE SOLVED: To execute the proper arrangement and wiring of power lines even for specific cells such as a micro-cell or soft macros, and to prevent standard cells strongly connected to each other from being arranged in circuit blocks different from each other. SOLUTION: This automatic arranging and wiring method comprises a step S1 for arranging specific cells such as macro cells in a specific region in the arrangement region of a semiconductor integrated circuit, a step S2 for arranging and wiring the first power line for supplying a power to the specific cells, a step S3 for dividing any region other than the specific region in the arrangement region into n pieces of divided regions so that the current consumption of the specific cells and the first power line can be well-balanced, a step S4 for dividing any circuit other than the circuit by the specific cells in a logic circuit constituted of the semiconductor integrated circuit into the n pieces of circuit blocks according to the logical connection and steps S5 to S10 for arranging the n pieces of circuit blocks in the n pieces of divided regions according to the logical connection of the logic circuit and current supply quantity to be supplied to the respective divided regions.
