Patent ID: 8336018

Claim:
A global power distribution network in an integrated circuit comprising: a first layer of conductive material (i) coupled to one or more power supplies and (ii) configured to form a plurality of first rails of a mesh, wherein said first rails (a) supply power to one or more components of a core logic of said integrated circuit, (b) are aligned with a first axis of said integrated circuit, and (c) have one or more parameters configured such that said mesh has a uniform voltage gradient from a perimeter of the integrated circuit to a center of the integrated circuit along said first axis; and a second layer of conductive material (i) coupled to said power supplies and (ii) configured to form a plurality of second rails of the mesh, wherein said second rails (a) supply said power to said components of said core logic, (b) are aligned with a second axis of said integrated circuit, (c) have one or more parameters configured such that said mesh comprises another uniform voltage gradient from said perimeter of the integrated circuit to said center of the integrated circuit along said second axis, (d) said parameters of said first rails comprise a width of each of said first rails and (e) said width of each of said first rails becomes thinner as said first rails are positioned closer to said center of said integrated circuit such that said first rail located nearest said center of said integrated circuit has a thinnest width and said first rail nearest said perimeter of said integrated circuit has a thickest width.
