1. A global interconnect distribution system, comprising:
- a global interconnect cell capable of producing at least two substantially identical output signals;
a global interconnect coupled to the cell for carrying one of the output signals;
at least one wire coupled to the cell that is routed adjacent to the global interconnect for carrying the other output signal to provide active shielding for the global interconnect, wherein the cell includes at least two output stages for generating the substantially identical output signals, wherein the global interconnect is coupled to a first one of the output stages and the active shielding wire is coupled to a second one of the output stages; and
at least one passive shielding wire patterned adjacent to the global interconnect, thereby increasing signal integrity and signal transmission of the global interconnect.

Abstract
A global interconnect distribution system is disclosed. The global interconnect distribution system includes a global interconnect cell capable of producing at least two substantially identical output signals, and a global interconnect coupled to the cell for carrying one of the output signals. At least one wire is also coupled to the cell that is routed adjacent to the global interconnect for carrying the other output signal to provide active shielding for the global interconnect, thereby increasing signal integrity and signal transmission of the global interconnect.
