Abstract
Disclosed are methods, systems, and articles of manufacture for characterizing electromigration effects in an electronic design. These techniques determine an electrical characteristic at a port of a portion of an electronic design and select a number of frequencies in the frequency domain for the electrical characteristic. Multiple electric currents through a circuit component in the portion may be determined at least by performing a number of analyses for the number of frequencies. An electromigration effect may be characterized for the circuit component by using at least the multiple electric currents.
