Patent ID: 8566762

Claim:
An integrated circuit design device that designs a three-dimensional integrated circuit with use of a standard cell library, the standard cell library being composed of a plurality of libraries that are each appropriate for a different temperature, the integrated circuit design device comprising: a temperature calculation unit operable to calculate, based on respective heat values and structure information pieces of respective chips forming layers constituting the three-dimensional integrated circuit to be designed, an operating temperature of a chip forming each of one or more target layers targeted for logic synthesis among the layers constituting the three-dimensional integrated circuit; a standard cell library selection unit operable to, for each of the target layers, select one library among the libraries that is appropriate for an operating temperature that is closet to and higher than the operating temperature of the chip forming the target layer calculated by the temperature calculation unit; and a logic synthesis unit operable to perform logic synthesis on each of the target layers with use of the library selected by the selection unit.
