Abstract
An information processing apparatus which includes a storage unit having stored a design data denoting layout and connection of a circuit, and a timing constraint data including a clock skew value denoting a delay difference allowed for a clock inputted to a pair of elements; a data read-out unit for reading out the design data and the timing constraint data; a clock skew value acquisition unit for acquiring the clock skew value set in correspondence with the pair of elements in layout in the circuit denoted by the design data from the timing constraint data; and a slack calculation unit for calculating a delay time between the pair of elements on the basis of the design data, and calculating a slack value indicating whether or not the pair of elements meets a predetermined design requirement by utilizing the acquired clock skew value and the calculated delay time with respect to the pair of elements.
