ABSTRACT:
When one net is wired, by restricting a wiring area, the net is efficiently wired in a short time. A wiring area setting unit sets a maximum rectangle including a set of terminals constructing the net into a wiring area. A wiring deciding unit decides the wiring between the nets so as to realize the shortest distance for the wiring area as a target. If a wiring violation or a non-connected terminal exists, a wiring area enlarging unit enlarges the present wiring area in accordance with a preset parameter and, thereafter, allows the wiring deciding unit to decide the wiring. With respect to a clip net in which in the case where one of a plurality of input terminals having the same function of cells is used, the non-used input terminals are wired as clip terminals to power terminals as well, a cell area is set into a wiring area and wired and if the wiring violation or non-connected clip terminal exists, the present wiring area is enlarged and the wiring is repeated.
