Recent research has proposed several low-power design techniques for VLSI circuitry in nano-scale CMOS era. However, these techniques always involve custom layout design or novel EDA flows. In this paper essential low power techniques such as voltage separation, body bias and power switch are implemented in existent place and route (P&R) tools. These techniques enable the possibility to integrated low power techniques into standard Cell-Based physical design flow. The result of these research shows a little overhead in design procedure equally area overhead compare with fully custom design flow. The proposed low power design techniques can be cooperated with modern power management system to enable the power reduction in targeting circuitry with small implementation overheads.
