CIRCUIT PLACEMENT WITH ELECTRO-MIGRATION MITIGATION

摘要

As method, executed by a computer, for placing circuit elements includes determining an initial placement for a set of circuit elements corresponding to a circuit design, identifying a port for a circuit element of the set of circuit elements to provide an identified port, calculating a load-to-driver capacitance ratio for the identified port, determining an estimated operating parameter corresponding to the identified port if the load-to-driver capacitance ratio exceeds a selected threshold, and changing placement of the circuit element, or an associated driver, if the estimated operating parameter is outside an acceptable operating range. Changing placement of the circuit element or an associated driver may improve the estimated operating parameter corresponding to the identified port. In some embodiments, the estimated operating parameter is an estimated operating temperature.
