In this conventional wiring layer and via type selection display system, the first wiring layer 81 and the second wiring layer 82 can be arbitrarily designated in the case of FIG. There is a problem that it is unavoidable that the wiring rate is remarkably reduced because layers such as No. 04 layer and No. 04 layer are not usually designated as a pair layer and layers that are not adjacent to each other can be designated.

Further, since the via type 83 can be arbitrarily selected from the via types prepared for the wiring board irrespective of the designated pair layer, the semi-penetration which should not be used in the designated pair layer. However, there is a problem in that the wiring board may not be manufactured when the via type is selected.

The object of the present invention is to solve the above-mentioned problems,
The specification of wiring layers that are not adjacent to each other, which is not usually specified as a pair layer, and the selection of via types that cannot be used in the specified pair layer are eliminated, and the reduction of the wiring rate and the inability to manufacture the wiring board are basically avoided. An object of the present invention is to provide a wiring layer and a via type selection display system that can be used.
