Abstract
A power integrity analyzer according to an exemplary aspect of the invention includes a parameter inputting unit that inputs parameters to a power-supply current waveform which indicates a variation of a power-supply current value on a time axis of an element, a conversion unit that converts the power-supply current waveform which indicates a variation on the time axis determined by the parameter to a power-supply current spectrum which indicates a variation of the power-supply current value on a frequency axis, an allowable value information storage unit that stores an allowable power-supply voltage fluctuation value of the element, and an impedance calculating unit that calculates a target impedance spectrum on the device indicating the variation of impedance value on the frequency axis based on the power-supply current spectrum and the allowable power-supply voltage fluctuation value.
