Abstract
Some novel features pertain to an integrated device that includes a first metal layer and a second metal layer. The first metal layer includes a first set of regions. The first set of regions includes a first netlist structure for a power distribution network (PDN) of the integrated device. The second metal layer includes a second set of regions. The second set of regions includes a second netlist structure of the PDN of the integrated device. In some implementations, the second metal layer further includes a third set of regions comprising the first netlist structure for the PDN of the integrated device. In some implementations, the first metal layer includes a third set of regions that includes a third netlist structure for the PDN of the integrated device. The third set of regions is non-overlapping with the first set of regions of the first metal layer.
