Detecting and addressing power side channels in semiconductor architecture and microarchitechture

A computer program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by a processor to cause the processor to perform operations comprising:

• determining a power consumption result of a hardware representative system comprising:
• constructing a power consumption relation based in part on an instruction;
• and
• generating executable code based on the power consumption relation wherein an output of executing the executable code comprises the power consumption result of the hardware representative system.
