A wiring information generating apparatus includes an input unit that inputs a wiring layer number indicating a wiring layer, a via layer number indicating a next via layer to connect the wiring layer, and spacing information based on wiring rules. A storage unit stores a terminal figure table providing terminal figures, a logic element device wire protected area table, and a wire protected area table. A wire protected area creation unit adds an area of a terminal figure and a logic element device wire protected area obtained by searching the terminal figure table and the logic element device wire protected area table based on the input wiring layer number and/or via layer number and acquires wire layer-via layer spacing information. A wiring information generating unit generates wiring information in the wiring layer based on connection information and arrangement information of the semiconductor logic circuit, and wire protected area information.
