Abstract
Some embodiments of the invention provide a method for performing thermal analysis of an integrated circuit ('IC') layout that includes numerous circuit modules. In some embodiments, the method initially defines several power dissipation equations that express the temperature dependence of the power dissipation for several circuit modules. In some embodiments, the power dissipation equations express a non-linear relationship between power dissipation and temperature. The method defines a heat flow equation based on the specified power dissipation equations. The method then solves the heat flow equation to identify a temperature distribution for the design layout.
