Abstract

Method and systems of powering on an integrated circuit (IC) are disclosed. In one embodiment, the system includes a region in the IC including functional logic, a temperature sensor for sensing a temperature in the region when the IC is powered up and a heating element therefor; a processing unit including: a comparator for comparing the temperature against a predetermined temperature value, a controller, which in the case that the temperature is below the predetermined temperature value, delays functional operation of the IC and controls heating of the region of the IC, and a monitor for monitoring the temperature in the region; and wherein the controller, in the case that the temperature rises above the predetermined temperature value, ceases the heating and initiates functional operation of the IC.
