Claim 10:
11. A method of testing a physical integrated circuit on a test circuit board, the method comprising:
performing, by a processor, a simulation of a first heat distribution throughout an integrated circuit design, the integrated circuit design including a set of circuit blocks and a set of heaters, the integrated circuit design being configured to operate at simulated design power levels, and to generate the first heat distribution, the simulated design power levels including configured power information, and the performing the simulation comprising:
determining a heat signature of the integrated circuit design from the configured power information and location information for each circuit block of the set of circuit blocks and each heater of the set of heaters included in the integrated circuit design, the heat signature including heat values distributed throughout the integrated circuit design;
determining whether the heat values of the heat signature of the integrated circuit design are within a heat range of the integrated circuit design; and
modifying the integrated circuit design in response to determining that the heat values of the heat signature of the integrated circuit design are not within the heat range;

manufacturing the physical integrated circuit according to the integrated circuit design; and
simultaneously performing a burn-in test of the physical integrated circuit and an automated test of the physical integrated circuit, the physical integrated circuit being configured to operate according to the simulated design power levels and being coupled to the test circuit board, wherein the burn-in test has a minimum burn-in temperature of the physical integrated circuit and a burn-in heat distribution across the physical integrated circuit.
