Placement aware functional engineering change order extraction

摘要

A computer implemented method for designing an integrated circuit includes receiving a netlist. The method also includes receiving physical layout information related to an integrated circuit based on the on the netlist and receiving an engineering change order (ECO) that changes at least one logical component of the physical layout. The method further includes forming two or more possible solutions to achieve the ECO, ranking the two or more possible solutions based on two or more factors and selecting the highest ranked solution.
