PURPOSE:To efficiently and effectively inspect wirings by providing means for indicating wirings for transmitting a positive signal or a reverse signal at wirings. CONSTITUTION:Wirings 1 are for transmitting a certain signal, and wirings 2 are for transmitting a reverse signal to the certain signal. The wirings 1 and 2 can be clearly distinguished according to figure feature 4 and 3. Thus, whether the wirings are for transmitting positive or reverse signal can be simply distinguished to readily inspect the types of the wirings on a layout drawings.
