PROBLEM TO BE SOLVED: To estimate current consumption of a mixed-signal circuit in a short time.;SOLUTION: A current consumption calculation device 100 acquires a value 113 of a digital signal input to an object circuit and a value 112 of an analog signal input to the object circuit together with the digital signal. The current consumption calculation device 100 extracts corresponding information 115 between each representative value of the analog signal and current consumption when the value 113 of the digital signal is input to the object circuit from a current consumption table 114 that indicates the current consumption of the object circuit when a combination of the value 113 of the digital signal and the representative value of the analog signal is input for each combination thereof. The current consumption calculation device 100 generates an interpolation function 116 for interpolating the current consumption of the object circuit corresponding to a value among individual representative values of the analog signal on the basis of the corresponding information 115 extracted and calculates current consumption 117 of the object circuit corresponding to the value 112 of the analog signal on the basis of the interpolation function 116 generated.;COPYRIGHT: (C)2013,JPO&INPIT
