Abstract
An integrated circuit (IC) can be configured to provide a managed power distribution to circuits within a plurality of regions of the IC. Each region of the plurality of regions can include a corresponding set of circuits that are electrically connected to a corresponding virtual power island (VPI) within said each region. A global power distribution structure within the IC can be configured to be electrically interconnected to an off-chip voltage supply. The IC can also include a plurality of sets of vertical interconnects (VIs), each set of VIs electrically interconnected to a VPI within a corresponding region. Each set of VIs can also be connected to the global power distribution structure, and can be used to provide a specifically managed voltage through a VPI to a set of circuits within a corresponding region of the IC.
