Power consumption analyzing apparatus and power consumption analyzing method

A power consumption analyzing apparatus has a clock gating cell detector configured to detect a clock gating cell which is not present in RTL data but present in a gate-level netlist, a test bench description generation unit configured to add a description concerning the clock gating cell, a monitor signal generation unit configured to specify a monitor signal used for power consumption analysis from the RTL data, an RTL simulation unit configured to execute operational simulation of the target circuit, a monitor unit configured to detect a logic of the monitor signal during the execution of the operational simulation, and a power consumption analysis unit configured to analyze power consumption.
