Multiple power supplies are required to power Xilinx devices. Separate sources provide the required power for different resources of the device. This allows different resources to work at different voltage levels for increased performance or signal strength while preserving a high immunity to noise and parasitic effects.
For power supplies available in Versal ACAP, refer Versal ACAP Resources and Corresponding Power Supply table in Xilinx Power Estimator User Guide for Versal ACAP (UG1275).
For power supplies available in other
Xilinx®
devices, refer FPGA Resources and their Power Supply table in
Xilinx
Power Estimator User Guide (UG440).
