Integrated Power Supply Reference Design for Xilinx Artix®-7, Spartan®-7, and Zynq®-7000 FPGAs


Design files


This reference design is a scalable power supply designed to provide power to the Xilinx Artix-7, Spartan-7, and Zynq-7000 families of FPGA-based devices. The design receives power from a standard DC power supply and provides power to all rails of the Xilinx chipset and DDR memory through a well-defined Samtec socket-terminal strip connection.

The design is scalable to support the most basic Spartan-7 FPGA device, a more complex Artix-7 FPGA with multi-Gigabit transceivers (MGTs), and up to the Zynq-7000 with a dual-core Arm Cortex-A9 processor. Due to its scalable design and the similarity of the Xilinx families of devices, this reference design is based on the TIDA-01480 power references design for the Xilinx Zynq UltraScale+ MPSoCs.

  • 13 hardware configurable power rails
  • Easy to change any output voltage in hardware
  • Only 1 input voltage required
  • Ideal power supply for the following Xilinx products: Artix-7 and Spartan-7 FPGAs, Zynq-7000 and Zynq-7000S SoCs
  • Small 3.5' x 2.5' PCB for use as a prototyping tool
