Abstract
The wiring method includes determining wirings based on a condition that one through-hole is formed; picking up a pair of wirings that are disposed on different layers and that need to be electrically connected to each other, from among the determined wirings, and extracting areas occupied by the wirings; making a decision about whether there exist areas that coincide with each other between the wirings; making a decision about whether the coincident areas have space sufficient for an additional through-hole; and setting an additional through-hole on the coincident areas with sufficient space.
