摘要

A computer determines a first relationship between a maximum frequency of the semiconductor device and an internal power supply voltage of the semiconductor device. Then, the computer determines a second relationship between the maximum frequency and an amount of noise, based on a number of the input/output signal pins. In addition, the computer estimates a fluctuation of the internal power supply voltage corresponding to a amount of noise of the semiconductor device, based on the first relationship and the second relationship. Then, the computer performs a design change of the semiconductor device based on the estimated fluctuation. And the computer stores the changed design of the semiconductor device to a storage device.
