PROBLEM TO BE SOLVED: To compute a consumed current or a power consumption in an integrated circuit in response to a logic condition of one or a plurality of internal signals within the integrated circuit. SOLUTION: This consumed current or power consumption arithmetic device has a condition inputting means 205 for inputting the logic condition of the internal signals within the integrated circuit, a storage means 208 for storing a consumed current data or a power consumption data per one operation estimated for each basic circuit cell within the integrated circuit, simulators 202, 203 for conducting logical simulation by a logic design data for the integrated circuit and a test bench to output the number of operations for the each basic circuit cell within the integrated circuit in response to the logic condition of the internal signals input by the condition inputting means, and an output means 206 for outputting a totalized consumed current or totalized power consumption in response to the number of operations for the each basic circuit cell output from the simulators and the consumed current data or a power consumption data of the each basic circuit cell stored in the storage means.
