For the same set of power densities, the HotSpot block and grid models give me different temperature values. Is there a bug?
Given identical grid structures (eg: a 3×5 grid shaped floorplan solved with a grid resolution of 3×5), both the block and grid models will give identical results. This is because they are solving the same set of equations through two different methods (matrix and iterative). However, for more general floorplans, the block and grid models are fundamentally different in their organization. The block model has a single temperature for the entire block while the grid model has one each per grid cell within a block. Differences are bound to arise when we try to substitute the multitude of temperatures with a single value. Depending on the application where HotSpot is used, this single value could be a simple average, weighted average, maximum, minimum or any other function of interest. In order to give flexibility to the user, HotSpot incorporates four choices – minimum, simple average, maximum and center. The ‘center’ function means that the temperature of a block reported by the grid mod
