Abstract: An embodiment includes an integrated circuit, comprising: a substrate; a first circuit formed on the substrate and coupled to a plurality of first pads on the substrate; and a second circuit formed on the substrate and coupled to a plurality of second pads on the substrate. The first pads are formed on a perimeter of the substrate; and the second pads extend from the perimeter of the substrate towards an interior of the substrate.

Abstract: Inventive aspects include a method, apparatus, and system for reducing power switch cells in MTCMOS circuits. Such may include disposing columns of real and virtual power straps orthogonally over rows of logic cells. A first power switch cell can be disposed over a real and a virtual power strap in a first column, and collinear with a first row of logic cells. A second power switch cell can be disposed over a real a virtual power strap in a second column, and collinear with a fifth row of logic cells. A third power switch cell can be disposed over a real a virtual power strap in a third column, and collinear with a third row of logic cells. A fourth power switch cell can be disposed over a real a virtual power strap in a fourth column, and collinear with a seventh row of logic cells.

Abstract: An embodiment includes a method, comprising: receiving a layout of an integrated circuit having a plurality of regions; determining a utilization for each of the regions; for each region, selecting from among a plurality of switch cell organizations for the region in response to the corresponding utilization; and for each region, modifying the layout to include switch cells for the region according to the selected switch cell organization.
