A method of designing a semiconductor device includes: calculating a design value of a noise parameter based on design specification of the semiconductor device. The noise parameter contributes to power-supply noise of the semiconductor device. The method further includes: setting the noise parameter variably within a predetermined range including the calculated design value; calculating amount of power-supply noise of the semiconductor device by using the set noise parameter; and generating a noise database indicating correspondence relationships between the noise parameter within the predetermined range and the calculated amount of power-supply noise.
