PROBLEM TO BE SOLVED: To enable it to verify a layout rule corresponding to working voltage only by using an actual process. SOLUTION: Two or more layers are provided with circuit constituents for integrated circuits where two or more working voltages are used, and among the two or more layers, a specific layer is dissociated is arranged with high voltage circuit constituents so that each layer may recognize its working voltage so as to verify the layout by applying the working voltage according the working voltage. It is made possible to perform the layout verification by the layout rules according to the working voltage, without generating newly a dummy layer etc. , only by using a layer used on an actual process, and by recognizing the circuit constituents applied with which a high voltage on a layout.
