Abstract: A method of generating a net-list for designing an integrated circuit device is provided, including generating a pin template file by laying out logic elements included in the integrated circuit device, generating a pin file by assigning a serial number to the logic elements and setting power names necessary for operating the logic elements, and generating a power inform template file by grouping an internal circuit of the integrated circuit device by a unit of power, generating a power inform file by combining the pin file with the power inform template file and arranging power information which is separately applied to each logic element, generating a final power inform file by assigning correct power names to power ports, to which power applied thereto is not defined, and completing a final net-list by combining core-related information of the integrated circuit device with the final power inform file.
