Abstract
An input unit receives circuit information on a circuit. A first calculating unit calculates delay-distribution information of a data path and delay-distribution information of a clock path, based on the circuit information. A second calculating unit calculates delay-difference-distribution information between the data path and the clock path by using the delay-distribution information of the data path and the delay-distribution information of the clock path. A third calculating unit calculates a clock-delay value of the circuit based on the delay-difference-distribution information.
