Xilinx Power Solution center - Design & Debug Assistant


Learn more about Power requirements when using Xilinx devices or to find help on debugging an issue related to Xilinx devices power you are currently encountering. 

The Design Assistant will walk you through the recommended design requirements for power requirements for Xilinx devices while debugging commonly encountered issues. 

The Power Design assistant will not only provide useful power requirement information but also point you in the exact documentation you need to read to help you design efficiency with respect to Xilinx devices power.

Note: The article is part of Power Solution Center. 

The Power solution center for Xilinx Devices available to address questions related to Power.

When you are starting new design with any Xilinx devices or trouble shooting any power related problems , then this Power solution center guide you and simplify work.


Unlike ASIC, in FPGA everything (IP cores, logic, IO standard, drive strength etc. all) is programmable.

So we are not able to publish power consumption in our documents because it is mostly dependent on the user design (Code) rather than the device part number.

However, to estimate the power in your FPGA Xilinx provides a complete solution that encompasses power estimators (XPE-Xilinx Power Estimator) and analyzers (XPA-Xilinx Power Analyzer), and power-driven implementation tool algorithms.

Please see (Xilinx Answer 57775) for more details to answer the below queries.

1. Why is the power consumption of FPGAs not published in Xilinx documents?
2. How can I determine the power consumption of an FPGA device?
3. How can I estimate the junction temperature of my design in FPGA?
