An object of this invention is to provide a wiring design method of integrated circuit device capable of determining a layout without such a problem as congestion of wirings efficiently upon determination of the wiring layout in the integrated circuit device, system thereof and program product thereof. In the wiring design method for determining the route of wiring between a cell and another cell in the integrated circuit device, first, a region in which wirings are to be placed is divided vertically and horizontally (S102). Which divided regions each wiring should cross is determined (S103). The numbers of the wirings crossing the border of each divided region are equalized (S104). If the length of a side of each divided region is larger than a predetermined length (No in S105), that region is further divided (S102). If the length of a side of each region is smaller than the predetermined length, the route at that time is adopted as the rough wiring route of each wiring (S106).
