PURPOSE:To allow efficient wiring by CAD by providing two lines of terminals whose positions in the height direction are the same as the terminals of other cells and providing wiring (WL, WL') which connects polycells in the area between the two terminal lines. CONSTITUTION:A unit block 20 has a height which is even in the Y direction and is composed of polycells 20a, 20b... whose widths in the X direction are different. The polycells are commonly provided with a source conductive body 201 in the X direction along the top side and a second power source conductive body 202 in the Y direction along the bottom side. For block 20, input/output terminals are arranged at the fixed height in the Y direction to form terminal lines C1 and C2. A wiring area WR is formed between the lines, and wiring conductive patterns WL, WL', etc., are formed in the wiring area WR being connected with the terminals 23. |
