We present a framework for combining Voltage Scaling (VS) and Gate Sizing (GS) techniques for power optimizations. We introduce a fast heuristic for choosing gates for sizing and voltage scaling such that the total power is minimized under delay constraints. We also use a more accurate estimate for determining the power dissipation of the circuit by taking into account the short circuit power along with the dynamic power. A better model of the short circuit power is used which takes into account the load capacitance of the gates. Our results show that the combination of VS and GS perform better than the techniques applied in isolation. An average power reduction of 73% is obtained when decisions are taken assuming dynamic power only. In contrast, average power reduction is 77% when decisons include the short circuit power dissipation.

In this paper we have introduced a new approach called Clock Gating and Voltage Scaling (CGVS), which is the combination of two existing techniques i.e. Clock gating and Voltage Scaling. Our aim is to design a low power Devnagari Unicode Checker (DUC) using CGVS technique. This design is implemented on Kintex-7 FPGA families, XC7K70T device, -3 speed grade and FBG676 package. From our analysis, it is observed that, with the use of clock gated technique in our target circuit and with the scaling of voltage from 1.0V to 0.1V, we are achieving clock power reduction of 98.98% on 10GHz and 1THz operating frequencies. Under same voltage scaling scheme, there is 6.66%, 10.38%, 10.64% and 10.62% less reduction in IO power, when the target circuit is operating on 1GHz, 10GHz, 100GHz and 1THz operating frequencies.
