By providing plural layers in which circuit components of an integrated circuit using plural voltages are arranged in accordance with used voltages, separately arranging the circuit component to which a high voltage is applied in a specific layer among the plural layers, recognizing the used voltage for each layer, and performing a layout verification by applying a condition in accordance with the used voltage, it is possible to recognize the circuit component, to which a high voltage is applied, on the layout, and to perform the layout verification using a layout rule in accordance with the used voltage using only the layers used in an actual process without newly generating a dummy layer etc.
