Leading in Power Innovation
Attain increased power advantages without compromising desired overall system performance with the latest Xilinx 7 series FPGAs. Power efficiencies realized through a 28nm high-performance, low power process, coupled with architecture innovations and simple and efficient power estimation tools. Xilinx provides a complete solution from IC technologies to software tools to help you optimize the total power consumption of your design.
7 Series FPGA Power Advantage
Providing superior performance per watt, 7 series FPGAs share scalable, optimized hardware architecture and are fabricated on a versatile 28nm high-k metal gate (HKMG) high performance, low-power process (28HPL) -- allowing Xilinx to deliver a full range of power-efficient FPGA product families. Xilinx 7 series FPGAs ensure that system designers can achieve power-optimized designs while meeting critical performance targets. The small, fast, low-power blocks of the 7 series architecture, refined over multiple generations and combined with an FPGA-optimized process, enable leadership power and performance for all FPGA workloads.
Realize your Power Advantage Today!
Available for all commercially available Xilinx FPGAs, the company provides a complete solution that encompasses power estimators and analyzers, power-driven implementation tool algorithms and a variety of power-related documentation.
Pocket Power Estimator (PPE) App
The Xilinx Pocket Power Estimator provides a quick, easy reference for calculating the reduced power consumption of Xilinx 28nm devices; compares Xilinx 7 series FPGAs to our previous generation families and approximates the power consumption of competitive families. The PPE app is now available through iTunes or in the Android Market.
Xilinx Power Estimator (XPE)
The Xilinx Power Estimator tool makes it easy to calculate your power advantage. We offer product-specific spreadsheet-based power estimation tools, delivering accurate and easy-to-use ways for you to quickly model the power consumption of your next design.
Vivado Power Analysis
The Vivado™ Design Suite provides accurate power analysis at every stage from synthesis to implementation. It provides graphical and textual views of the power consumption by design hierarchy, types of blocks (such as clock trees, signals, hard IPs, logic, Block RAMs, DSPs) and voltage rails. It also provides thermal properties for the design under specified operating conditions. Vivado offers excellent cross-probing capabilities from the power report to the user design in HDL form, schematics or the FPGA device view with a single key stroke. Vivado power optionally accepts VCD and SAIF files from simulation tools to read in the switching activity and provide a more accurate power estimate for the design. Users can subsequently perform what-if analysis by varying the switching activity at different nodes to simulate various scenarios for the design.
Vivado Power Optimization
The Vivado Design Suite offers push button power reduction using proven ASIC technology for FPGA. This technology saves up to 30% dynamic power by automatically turning off unused portions of the design. Designers can use this fine-grained clock gating technology without requiring device architecture expertise allowing Vivado to optimize the entire design for power savings or provide directives to optimize only portions of the design through simple XDC constraints.
ISE Power Tools
The ISE Design Suite includes exclusive tools and technologies to predict, achieve, and validate optimal power savings. ISE Design Suite offers a simple, one-step process to specify power optimization. Delivered with ISE Design Suite, Xilinx Power Analyzer provides accurate power analysis after design implementation, highlighting areas in the design for potential power reduction.
