Abstract:
1. An integrated circuit (IC), comprising; a long distance power and ground distribution network disposed within an interior portion of the IC for power and ground distribution to core circuitry resident within the interior portion of the IC; an input/output (I/O) power and ground distribution network disposed along outer edges of the IC and electrically localized for coupling to select number of localized I/O circuits that are also disposed along the outer edges of the IC, in which each localized I/O power and ground distribution portion of the network is electrically coupled to the long distance power and ground distribution network, wherein both long distance power and ground distribution network and I/O power and ground distribution network are located within upper level conductive layers, and wherein each localized I/O power and ground distribution portion of the network is operable to locally supply power and ground to corresponding local I/O circuits; and a plurality of macro processing circuits also disposed along outer edges of the IC, wherein the macro processing circuits are located within lower level conductive layers.
