System and method of electromigration avoidance for automatic place-and-route

摘要

A method includes identifying at least one local power segment of a circuit, estimating at least one performance parameter of the at least one power segment based on a computer-based simulation of the circuit, and changing a design of the circuit based on at least one electromigration avoidance strategy if the at least one parameter is greater than or equal to a threshold value. A data file representing the circuit is stored if the at least one parameter is less than the threshold value.

1. A method, comprising:
identifying at least one local power segment of a circuit; dividing an area occupied by devices supplied by the at least one local power segment into a plurality of cells, wherein each cell has a respective power consumption and a respective area that is based on the respective power consumption such that the power consumptions of each of the plurality of cells are approximately equal; estimating at least one performance parameter of the at least one local power segment based on a computer-based simulation of the circuit; making a design change in the circuit based on at least one electromigration avoidance strategy if the at least one parameter is greater than or equal to a threshold value, wherein the design change affects at least one cell of the plurality of cells; and storing a data file representing the circuit if the at least one parameter is less than the threshold value.
