Patent ID: 7483806

Claim:
A design structure embodied in a machine readable medium for designing, manufacturing, or testing a design, the design structure comprising: a system of powering on an integrated circuit (IC), the system comprising: a plurality of regions in the IC, each region including functional logic, a temperature sensor, a heating element therefor and a predetermined temperature value therefore, 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; 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; and wherein in the case that a particular region does not attain the predetermined temperature value after a set number of attempts, the controller controls heating of a previously unheated proximate region that is in close proximity to the particular region.
