PURPOSE:To determine a print pattern easily by performing allocation to an actual pattern generation layer and a generation area in a virtual print pattern generation area wherein the print pattern generation layer and generation area are combined. CONSTITUTION:The print pattern generation layer 2 which has the same print pattern direction 1 is combined with the generation area 3 as one loop to form the virtual printed board having an overlap area 4; and a print pattern for the board is determined by a conventional wiring method and then the amount of the print pattern of the overlap area 4 is checked. when the amount of the print pattern is larger than a permissible value and when wiring among all parts is completed, the pattern is extracted; when the amount of the print pattern is larger than the permissible value, the overlap area 4 of the virtual printed board is corrected to perform the allocation to the actual pattern generation layer and generation area. |
