PROBLEM TO BE SOLVED: To provide a power supply wiring design method and a power supply wiring design system that can reduce a workload of power line preprocessing before timing closure. SOLUTION: Power line processing is divided into power line preprocessing S23 before timing closure S24 and power line postprocessing S25 after the timing closure S24. The power line preprocessing S23 comprises branch power line generation and main power line generation, and the power line postprocessing S25 comprises usable area extraction S25-1, wiring graphic generation S25-2 and connection relationship generation S25-3. Operations related to the power line preprocessing S23 before the timing closure S24 are the branch power line generation and main power line generation, and the usable area extraction S25-1, wiring graphic generation S25-2 and connection relationship generation S25-3 are after the timing closure S24.
