1.6. Testing the Hardware Design Example

Follow these steps to test Ethernet-based design examples in hardware:
  1. Generate design example as described in Generating the Design.
  2. Modify the .qsf settings:
    • Set device to match the appropriate ordering part number (OPN) for your design.
    • Update the pinout to match the board and the design function.
    • Assign the appropriate VID settings in your .qsf file to match your board.
  3. Generate the .sof file.
  4. Update board clock settings. The default value for the PHY reference clock is 156.25 MHz. The default value for the reconfiguration clock is 100 MHz.
  5. Insert appropriate electrical loopback plug into the Ethernet port.
  6. Program the design.
  7. Open Tools > System Debugging Tools > System Console.
    1. Navigate to the hardware directory <design_example>/hardware_test_design/hwtest directory.
    2. Type source main_<variant_type>.tcl.
    3. Type set_jtag<number_of appropriate_JTAG_master>
      Note: If you enabled auto-negotiation and link training in your design, follow the hardware design example steps described in Hardware Design Example.
    4. Run the following command:
      run_test_without_loopback

The hardware design example uses run_test command to initiate packet transmission from packet generator to the IP core. The script enables internal loopback, checks the PMA PHY status, sends 16 packets, and displays the MAC statistics. When you use run_test_without_loopback command to run the hardware test, the script disables the internal loopback.

The following sample output illustrates a successful hardware test run:
