Abstract
A computer implemented method comprises accessing a 3D-IC model stored in a tangible, non-transitory machine readable medium, processing the model in a computer processor to generate a temperature map containing temperatures at a plurality of points of the 3D-IC under the operating condition; identifying an electromigration (EM) rating factor, and calculating and outputting from the processor data representing a temperature-dependent EM current constraint at each point.
