Abstract
Embodiments of systems and methods for leakage reduction of a cell are presented herein. According to one embodiment, a path module can identify each rail-to-rail path in a cell. In the embodiment, a transistor set module can select one or more transistors that are coupled to a rail of the cell and, if removed, no rail-to-rail path would exist in the cell. A layout modification module can transform the cell by upsizing a gate length of each transistor of the selected transistors to create a low-leakage version of the cell.
