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.
