Claim 19:
20. A non-transitory machine readable medium storing executable program instructions which when executed by a data processing system cause the data processing system to perform a method, the method comprising:
retrieving from memory, based on whether a thermal behavior of a given tile of an integrated circuit (IC) to be predicted is located at a corner of the IC, along a border of the IC, or within an interior of the IC, one of a plurality of trained neural network models, each of the trained neural network models having been trained with a plurality of inputs and an output derived from a thermal simulation of a corresponding portion of the IC identified by a respective one of a plurality of predetermined templates, each one of the predetermined templates comprising a plurality of tiles and identifying the portion of the IC as being located at corners of the IC, along the border of the IC, or within the interior of the IC according to the plurality of the tiles of the predetermined template, the plurality of inputs comprising a relationship between a change in a temperature relative to a power, and a sequence of time-power-temperature tuples; and
determining, using the retrieved trained neural network model, the thermal behavior of the given tile of the IC for a selected time period, a plurality of inputs to the retrieved trained neural network model including: (1) a selected relationship between a change in temperature relative to a power applied to the IC in the thermal simulation, (2) the portion of the IC identified by the predetermined template associated with the retrieved trained neural network model, (3) a selected power pattern for the given tile and (4) a selected current uniform time-dependent temperature of the IC.
