PROBLEM TO BE SOLVED: To simply analyze circuit delay variation distribution. SOLUTION: A method for analyzing delay time variation of a circuit including N-stage elements is provided. The method includes a delay time calculation step for calculating a maximum deviation delay time of a signal that propagates the circuit and a basic delay time of the circuit, a delay variation calculation step for calculating a delay variation value of the N-stage circuit, using N-stage mean squares of differences between the maximum deviation delay time of the circuit and the basic delay time of the circuit, and a step for generating the delay time distribution of the N-stage circuit as normal distribution, using the calculated delay variation value.
