Circuit placement with electro-migration mitigation

摘要

A 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 can improve the estimated operating parameter corresponding to the identified port. In some embodiments, the estimated operating parameter is an estimated operating temperature.

主权项

1. A computer program product for placing circuit elements in a circuit design, the computer program product comprising:
one or more non-transitory computer readable storage media and program instructions stored on the one or more non-transitory computer readable storage media, the program instructions that, when executed by at least one computer, cause said at least one computer to perform a process for placing circuit elements, the program instructions comprising instructions configuring a processor unit of said at least one computer to: determine an initial placement for a set of circuit elements corresponding to a circuit design; identify a port for a circuit element of the set of circuit elements to provide an identified port; calculate a load-to-driver capacitance ratio for the identified port; determine an estimated operating parameter corresponding to the identified port if the load-to-driver capacitance ratio exceeds a selected threshold; and change placement of the circuit element, or an associated driver, if the estimated operating parameter is outside an acceptable operating range.
