Abstract: A dynamic power consumption estimation method includes recording a statistical value of each of n target signals of a to-be-measured target in a unit time, where the target signal is a clock signal obtained after clock gating and the statistical value is a quantity of times toggling, or the target signal is a clock gating signal and the statistical value is a quantity of enable cycles, and calculating the dynamic power consumption of the to-be-measured target in the unit time based on the statistical value of each of the n target signals in the unit time.
