  • Patent number: 6835972
    Abstract: A multiple layer power mesh design includes an L-shaped structure and a bow tie-shaped structure. The L-shaped structure provides a plurality of L-shaped power rails in each of four quadrants of the layer. The bow tie-shaped structure includes plurality of vertical power rails in each of a left and right triangularly-shaped portion of the layer. The vertical power rails of the bow tie-shaped structure provide and interface between the upper and lower quadrants of the L-shaped layer. The bow tie-shaped structure provides additional available space which can, for example, be used for routing signal traces. A T-shaped structure is also provided for use with the bow tie-shaped layer. The T-shaped layer provides for improved distances between the VDD and the VSS power rails.

  • Patent number: 6781228
    Abstract: A multiple layer mesh design which includes a layer which provides a vertical mesh and an adjacent layer which provides a horizontal mesh which includes an open area or hole. The layer which provides the horizontal mesh (with hole) may either be above or below the vertical mesh layer, depending on the design. The vertical mesh may be full or may surround an open area or hole where the design includes both a horizontal donut mesh and a vertical donut mesh.

  • Publication number: 20040124521
    Abstract: A rectangular termination ring for a power distribution mesh is placed on the upper two layers of an integrated circuit and may be placed over some I/O circuitry. The strapping connecting the bonding pads to the termination ring are placed on upper levels of the integrated circuit, minimizing the via requirements and freeing space for additional circuitry. Further, the termination ring may be adapted to work in conjunction with L-shaped, as well as other power distribution meshes.
