Abstract
A method for determining signal electromigration in a circuit includes selecting partitions from a netlist of the circuit is provided, each of the partitions including independent signal paths. The method includes determining a size of a partition, applying input vectors to a signal path in a large partition to obtain a signal toggle in an output, determining a current in the signal path, and identifying an electromigration result from the current flow. The method includes generating an output database for the partition, comprising an electromigration result for the first component, and combining the output database for the partition with a second output database from a second partition, the second output database including a second electromigration result for a second component in the second partition to generate an electromigration report for the netlist of the integrated circuit.
