1. A method of performing a thermal analysis of an integrated circuit device, comprising the steps of: reading and parsing integrated circuit device layout data; directing a conversion program to input instructions for a finite element analysis program to generate predetermined thermal source areas based on the integrated circuit device layout data; directing the conversion program to input instructions for the finite element analysis program to partition the integrated circuit device into thermal source areas by performing Boolean operations; directing the conversion program to input instructions for the finite element analysis program to generate a finite element mesh of the integrated circuit device; collecting information about operating conditions from a user; directing the conversion program to input instructions for the finite element analysis program to perform a thermal analysis of the integrated circuit device based on the information collected about operating conditions; executing the analysis program; and producing thermal analysis data via execution of the analysis program based on the operating conditions supplied by the user.
