Meeting power and thermal budgets is one of the essential criteria by which our customers measure the success of their FPGA-based system designs. Constrained both by the density (bandwidth, logic density, and functionality) of the applications they are creating and the environments in which these systems are deployed, FPGA designers need every advantage as they painstakingly balance performance, cost, reliability, and power.

Xilinx demonstrated its commitment to empower its customers- success with the introduction of the Virtex-4 family of FPGAs. Delivering the lowest total power in any 90 nm high-performance FPGA without compromising performance (1 to 5W lower than any competing 90 nm device), Virtex-4 devices employ a variety of powersaving design techniques to provide the lowest inrush current, static power, and dynamic power. (For more details about the Virtex-4 power advantage, please see “Power vs. Performance: The 90 nm Inflection Point” in the August 2005 issue of the Power Management Solution Guide, www.xilinx.com/solguides.)

This substantial power advantage provided by Virtex-4 devices translates directly to additional measurable benefits in performance, cost, and reliability. Reducing the FPGA’s contribution to total power in a given design alleviates a host of problems incurred by excessive power.
