The present disclosure provides reducing clock power consumption of a computer processor by simulating, in a baseline simulation of a computer processor design using a software model of the computer processor design, performance of an instruction by the computer processor design, to produce a baseline result of the instruction, and identifying a circuit of the computer processor design that receives a clock signal during performance of the instruction, and in a comparison simulation of the computer processor design using the software model of the computer processor design, simulating performance of the instruction by the computer processor design while injecting a corruption signal into the circuit, to produce a comparison result of the instruction, and designating the circuit for clock gating when processing the instruction, if the comparison result of the instruction is identical to the baseline result of the instruction.
