The present invention provides a semiconductor integrated circuit device that reduces the influence of crosstalk noise and is operable properly even when relatively long signal wirings that pass over a macrocell are formed. In the semiconductor integrated circuit according to the present invention, buffering cells formed between the macrocell and an input/output circuit close thereto are connected to their corresponding signal wirings extended so as to pass over an area formed with the macrocell.
