ABSTRACT:
A method for wiring a semiconductor integrated circuit device includes a first step of assigning wiring routes for globally wiring cells of a plurality of cell rows to the cell arrays and the channel regions, in accordance with a wiring request for realizing a predetermined circuit operation, so as to obtain a plurality of nets, a second step of extracting X lines, extending along the channel regions, from the nets, a third step of combining the X lines in a plurality of line groups, in accordance wich X-coordinates of the X lines, and assigning the line groups to tracks of the channel regions, and a fourth step of determining a position of at least one cell row through which a Y line of the net passes, in order to connect the cells corresponding to the nets via the corresponding X lines.
