Abstract
An integrated circuit includes a plurality of thermal sensors integrated within digital domain circuitry and powered by a digital supply voltage. An activation register receives activation data from a tester unit. Control logic, in response to the activation register being written with the activation data, enters a thermal calibration mode, deactivates a plurality of digital logic units of the digital domain circuitry, and causes a reference clock received from the tester to drive the plurality of the thermal sensors.
