摘要

An apparatus of the present invention computes delay times of logic paths included in a logic circuit which has a plurality of elements whose output is determined by the input of a clock signal and at least one signal which is not the clock signal. The apparatus includes: a first element which stores information about the logic circuit; a second element which groups pairs of two elements into groups based on a clock skew range value between the elements in each of the pair groups; and a third element which computes a delay time for each of the groups grouped by the second element by using a predetermined clock skew value related to the range used in the second element and the information about the logic circuit stored in the first element.
