1.8. Testing the Hardware Design Example

After you compile the Low Latency 100G Ethernet Intel Stratix 10 FPGA core design example and configure it on your Stratix® 10 device, you can use the System Console to program the IP core and its embedded Native PHY IP core registers.

To turn on the System Console and test the hardware design example, follow these steps:

  1. After the hardware design example is configured on the Stratix® 10 device, in the Quartus® Prime Pro Edition software, on the Tools menu, click System Debugging Tools > System Console.
  2. In the Tcl Console pane, type cd hwtest to change directory to <design_example_dir>/hardware_test_design/hwtest.
  3. Type source main.tcl to open a connection to the JTAG master.

You can program the IP core with the following design example commands:

  • chkphy_status: Displays the clock frequencies and PHY lock status.
  • chkmac_stats: Displays the values in the MAC statistics counters.
  • clear_all_stats: Clears the IP core statistics counters.
  • start_pkt_gen: Starts the packet generator.
  • stop_pkt_gen: Stops the packet generator.
  • loop_on: Turns on internal serial loopback
  • loop_off: Turns off internal serial loopback.
  • reg_read <addr>: Returns the IP core register value at <addr>.
  • reg_write <addr> <data>: Writes <data> to the IP core register at address <addr>.
The successful test run displays output confirming the following behavior:
  1. Turning off packet generation
  2. Enabling loopback
  3. Waiting for RX clock to settle
  4. Printing PHY status
  5. Clearing MAC statistics counters
  6. Sending packets
  7. Reading MAC statistics counters
  8. Printing MAC statistics counters, which show 0 in all error counters

The following sample output illustrates a successful test run:
