PROBLEM TO BE SOLVED: To estimate dispersion of a delay in an LSI in a design step for easily and surely reflecting the estimation result to delay simulation of the LSI. SOLUTION: A statistical delay simulation device 10 is provided with a circuit simulator 11 simulating circuit operation of a circuit cell constituting the LSI, a statistical delay library creation device 12 creating a statistical delay library 104 describing dependency of delay dispersion in each circuit on a predetermined operation condition according to a process parameter 101 and the like, a delay calculator 13 calculating a delay quantity of each circuit cell and creating a statistical LSI delay information file 107 including the delay data, and a static timing analyzer 15 simulating operations including the delay dispersion of the LSI on the basis of the data of the statistical LSI delay information file 107 and creating a statistical LSI delay analysis result file 108.
