Abstract:
1. A method for performing thermal analysis of a semiconductor chip design, the method comprising: constructing a coarse grid operator in accordance with one or more physical attributes of said semiconductor chip design, said coarse grid operator comprising a plurality of grids representing at least a portion of said semiconductor chip design, where said constructing comprises, constructing a first grid, said first grid comprising a first plurality of control volumes, and applying coarsening to said first grid in order to produce at least a second grid, said second grid comprising a second plurality of control volumes that is fewer in number than said first plurality of control volumes, where each of said second plurality of control volumes contains at least two of said first plurality of control volumes; and calculating, using said coarse grid operator, temperatures of said at least a portion; wherein a three-dimensional temperature model of said at least a portion is produced, at least in part, by said calculating.
