PURPOSE:To enable to rapidly decide a wiring ranging from its one end to its other end without spending a wasteful labor hour by a method wherein a clearance with the prescribed interval to the segments for the wiring route decided at first is set on the inner side of the wiring region and a new wiring region boundary line is formed. CONSTITUTION:Before the first wiring route is decided, a boundary line 2 with a clearance to the frame of a wiring region 1 is formed on the periphery of the inner side of the wiring region 1. After that, after segments, which are used as the wiring ranging from a starting end Si to a terminal Ti, are decided according to the prescribed procedures, segments bi1, Bi2...bil parallel to the segments decided are formed in the residual wiring region in such a way as to have a clearance width to the segments decided for setting a clearance for the following wiring to be formed adjacent to the wiring decided at first. A boundary line 3 to show the residual wiring region is anew formed from both of the segments bi1...bil formed according to these procedures and the boundary line 2 formed at first. This boundary line 3 gives a direction needed for deciding the following wiring route. |
