Abstract
Sleep transistors in industrial power-gating designs are custom designed with an optimal size.
Consequently, sleep transistor P/G network optimization becomes a problem of finding the optimal
number of sleep transistors and their placement as well as optimal P/G network grids, wire widths
and layers. This paper presents a fake via based sleep transistor P/G network synthesis method,
which addresses the requirements from industrial power-gating designs. The method produces
optimal sleep transistor P/G networks by simultaneously optimizing sleep transistor insertion and
placement as well as the power network grids and wires for minimum area, maximum routability
with a given IR-drop target.
