9: Perform DMA for Throughput N/A No No Yes
For link stability when running the design examples on the Intel® Stratix® 10 DX FPGA Development Kit or the Intel® Agilex™ F-Series FPGA Development Kit, set the PCIe refclk switch to select the common refclk from the PCIe Edge Connector.
  • For the Intel® Stratix® 10 DX FPGA Development Kit, set SW14 to the OFF position to select the common refclk with the PCIe Host.
  • For the Intel® Agilex™ F-Series FPGA Development Kit, set SW7.1 to the OFF position to select the common refclk with the PCIe Host.
