ABSTRACT:
A method of verifying a semiconductor integrated circuit is provided. A controlling cell and a controlled cell controlled by a control signal output from the controlling cell are placed in an IO region of the semiconductor integrated circuit. The method includes: (A) providing a library that includes requirement information specifying the controlling cell required by the controlled cell; (B) obtaining a region information indicating a region within the IO region in which a signal interconnection through which the control signal is transmitted is provided; and (C) verifying whether or not the specified controlling cell is placed within the region, in a case where the controlled cell is placed within the region.
