Title: Power supply circuit diagram design system

Abstract: A data library, a CPU and a memory store a design aid program which designs power supply circuit diagrams based on the data library in accordance with given conditions for a power supply circuit. Therefore, design errors associated with an increased design scale are prevented and the design time is shortened. The given conditions are taken as the respective vertical and horizontal intervals between power portions having first pins for connecting to a power supply and second pins for connecting to earth, and the number of rows and the number of steps of the power portions. Then, multiple available power portions are arranged according to the given conditions by a design aid program and the multiple arranged power portions are wired to a power supply symbol and an earth symbol, respectively.
