- necessary power source information voltage type, power consumption, size, etc.
- Step S2 The tree information creation unit 4 acquires device information. At this time, when the device information is stored in the device information storage unit 3a as a library, the tree information creation unit 4 acquires the corresponding device information from the device information storage unit 3a. If the corresponding device information is not stored in the device information storage unit 3a, the tree information creation unit 4 requests the user to input the device information in a predetermined data format.

The current value, voltage value, and path width are output to the display unit 5 as characteristic value information.
- the path width calculation uses information such as the copper foil thickness, through-hole diameter, and through-hole plating thickness included in the board information. For example, since a voltage 12V and a current 10A flow through the power path 23a, it is assumed that the necessary path width is calculated as 10 mm from the thickness of the copper foil included in the board information. Further, it is assumed that the path width of the power path 23b is calculated to be 20.5 mm when the power output from the power source 21 is DC 3.3V, 30A. Therefore, the tree information creation unit 4 divides the calculated value into a plurality of stages and sets a path width for each stage.

An instruction as to whether or not the display content is “OK” is given by the user viewing the display screen. If it is determined that the design is as designed, the display content “OK” is instructed, and the process ends. On the other hand, when the design is changed, the display content “NO” is instructed. Thereby, the process returns to step S1.
