1. A computer program product comprising a tangible computer readable storage medium having computer readable program code embodied therewith, said computer readable program code comprising: computer readable program code configured to generate a single finite element mesh for predicting performance of an integrated circuit design; computer readable program code configured to identify a plurality of sample points for conducting a variability study on at least one parameter associated with said integrated circuit design, said sample points being selected to predict performance of said integrated circuit design when subject to variations in said at least one parameter due to variations in manufacturing processes to be used to manufacture said integrated circuit design; computer readable program code configured to generate a parameterized netlist corresponding to each of said sample points; computer readable program code configured to run a technology computer aided design simulation for each of said parameterized netlists, using said single finite element mesh for each of said parameterized netlists, wherein said single finite element mesh remains unchanged for different parameters of each of said parameterized netlists, until convergence is achieved, to obtain, for each of said parameterized netlists, at least one metric indicative of said performance of said integrated circuit design; and computer readable program code configured to develop a predicted design yield for said integrated circuit design, based on said at least one metric determined for each of said parameterized netlists.
