摘要： Embodiments are provided for providing enhanced fabrication and design of an integrated circuit in a computing system by a processor. One or more latches may be clustered by augmenting an integer linear program (“ILP”) operation with a facility-location allocation (FLA) operation, wherein the clustering of the one or more latches is timing-aware. The one or more latches may be placed and assigned in the integrated chip based on clustering one or more latches.

摘要： Embodiments are provided for providing enhanced routing in a computing system by a processor. One or more of a plurality of short nets in a cell of an integrated circuit may be aligned for executing a routing operation, wherein a short net is a two-pin net having two gates on adjacent rows having a horizontal distance less than a selected threshold.
