  • Clock distribution network wiring structure
    Patent number: 7831946
    Abstract: A wiring structure for clock signals has two or more parallel clock signal wires disposed in adjacent power wire bays that span the distance between the sinks to which the clock signal wires are to be coupled. The parallel clock signal wires are shorted one to another by stubs placed at locations in order to time the clock wiring structure. The delay tuning of the structure is obtained by the discrete movement of wiring stubs between the wiring bays of the pre-defined power grid.
    Type: Grant
