I did not realize the datasheet uses a different term for hidden power. Your understanding about hidden power is basically correct. There are some settings that controls how hidden-power or power in general is calculated. If the hidden power changes with simulation time, it may be that the circuit has not been fully initialized to a stable state. in some cases, forcing the power_time to the trans_time may help. Or, you may have to check if extra efforts/settings are needed to initialize the circuit. You should be able to find this out from standalone Spectre simulation and waveform, using the saved deck and powe_info_* settings. If the hidden power increases linearly with simulation time, it could be that the leakage has not been subtracted. Regards, Guangjun
