    • PROBLEM TO BE SOLVED: To efficiently perform circuit delay verification for predicting a maximum operating frequency for a semiconductor integrated circuit being designed, in consideration of manufacturing variations of the semiconductor integrated circuit. SOLUTION: A circuit delay verification device 10 for a semiconductor integrated circuit includes: a variation delay sensitivity generation means for deriving a variation delay sensitivity characteristic; a circuit scale information management means for deriving a circuit scale characteristic; an operating frequency information management means for deriving an operating frequency characteristic; an unconsidered delay time generation means for generating an unconsidered delay time characteristic; and a circuit delay time calculation means for generating a circuit delay time characteristic in consideration of manufacturing variations in the semiconductor integrated circuit, from the variation delay sensitivity characteristic, the circuit scale characteristic, the operating frequency characteristic and the unconsidered delay time characteristic, and managing the generated circuit delay time characteristic. The generated circuit delay time characteristic is used to perform circuit delay verification for the semiconductor integrated circuit. COPYRIGHT: (C)2010,JPO&INPIT
