2.1.2.3. Recommended Power Tree for the Agilex™ 7 AGM (with only F-Tile, or both F-Tile and R-Tile) Device Packages

Figure 3.  Recommended Agilex™ 7 AGM (with only F-Tile, or both F-Tile and R-Tile) Power Tree for Engineering Sample (ES) Silicon This power tree demonstrates the recommended FPGA PCB power rails grouping. You can use any recommended voltage regulators listed in the FPGA Core Fabric VCC Voltage Regulator Selection section as long as they meet the power rail specifications listed in the Agilex™ 7 AGM Devices with only F-Tile, or both F-Tile and R-Tile PCB Power Rail Tolerance table.
  • This block diagram is also applicable for the Agilex™ 7 AGM devices with only F-Tile (Only FGT transceivers enabled) in the package. However, you need to remove or disable all power rails in the power tree with power rails ending with _GXR and _FHT_GXF to exclude the R-Tile and F-Tile (FHT) from the power tree. For more information, refer to the Unused R-Tile and F-Tile Channels section.
  • All power rails with naming _GXR refers to the R-Tile power rails and all power rails with naming _GXF refers to the F-Tile power rails.
