Design structures, method and systems of powering on integrated circuit

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 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 of each region against a respective predetermined temperature value therefor,
• a controller, which in the case that the temperature is below the predetermined temperature value for at least one region, delays functional operation of the IC and controls heating of the at least one region of the IC,
• a monitor for monitoring the temperature of each region that is below the predetermined temperature value;
• and
• wherein the controller, in the case that the temperature of each region rises above the predetermined temperature value therefor, 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.
