Abstract
A method detects active power dissipation in an integrated circuit. The method includes receiving a hardware design for the integrated circuit having one or more clock domains, wherein the hardware design comprises a local clock buffer for a clock domain, wherein the local clock buffer is configured to receive a clock signal and an actuation signal. The method includes adding instrumentation logic to the design for the clock domain, wherein the instrumentation logic is configured to compare a first value of the actuation signal determined at a beginning point of a test period to a second value of the actuation signal determined at a time when the clock domain is in an idle condition. The method includes detecting the clock domain includes unintended active power dissipation, in response to the first value of the actuation signal not being equal to the second value of the actuation signal.
