This paper studies power modeling for field programmable gate arrays (FPGAs) and investigates FPGA power characteristics in nanometer technologies. Considering both dynamic and leakage power, a mixed-level power model that combines switch-level models for interconnects and macromodels for look-up tables (LUTs) is developed. Gate-level netlists(More)
Power optimization is of growing importance for FPGAs in nanometer technologies. Considering dual-Vdd technique, we show that configurable power supply is required to obtain a satisfactory performance and power tradeoff. We design FPGA circuits and logic fabrics using configurable dual-Vdd and develop the corresponding CAD flow to leverage such circuits and(More)
Device optimization considering supply voltage Vdd and threshold voltage Vt tuning does not increase chip area but has a great impact on power and performance in the nanometer technology. This paper studies the simultaneous evaluation of device and architecture optimization for FPGA. We first develop an efficient yet accurate timing and power evaluation(More)
This paper describes a non-volatile reprogrammable FPGA fabric, whose configuration data are provided directly by flash memory. The fabric is optimized for low-cost, low-power applications, leveraging the density of flash and the elimination of conventional configuration SRAM and its attendant static power. After surveying the necessary background on flash(More)
In this paper we study the technology mapping problem of FPGA architectures with dual supply voltages (Vdds) for power optimization. This is done with the guarantee that the mapping depth of the circuit will not increase compared to the circuit with a single Vdd. We first design a single-Vdd mapping algorithm that achieves better power results than the(More)
Power has become an increasingly important design constraint for FPGAs in nanometer technologies, and global interconnects should be the focus of FPGA power reduction as they consume more power than logic cells. We design area-efficient circuits for programmable fine-grained power-gating of individual unused interconnect switches, and reduce interconnect(More)
As semiconductor technology scales down, the leakage power will soon become comparable to the dynamic power. To reduce both dynamic and leakage power, power gating in addition to clock gating should be used because clock gating saves only dynamic power. The knowledge of maximum current is needed to design high-performance and reliable circuits using power(More)
This paper presents a technology mapping algorithm for field-programmable gate array architectures with dual supply voltages (Vdds) for power optimization.
