  • Patent number: 8789000
    Abstract: A system and design methodology for performing routing in an integrated circuit design is disclosed. An integrated circuit design is first created using standard cells having metal level 2 (M2) power rails. Routing is performed and power rail current density for the integrated circuit is computed. Standard cells that have power rail current density below a predetermined threshold are replaced with a functionally equivalent standard cell that does not have M2 power rails, and the routing operation is performed again, until the design converges.
