2.5. Hardware Testing

After you download the design and the accompanying software into the FPGA, you can test the design through an interactive session. The interactive session provides helpful statistics, and enables you to control various aspects of the design.

You can control the following operations by entering the option numbers listed below:

  • 0) Toggle Loopback Mode — Toggles TX to RX serial loopback path within the transceiver or external loopback mode. By default, the design example is set to external loopback mode. The loopback mode is specified in the interactive session. Disable the traffic generator/checker before switching loopback modes to avoid transmission error.
  • 1) Enable Data Generator/Checker — Enables the traffic generator and start sending out data.
  • 2) Disable Data Generator/Checker — Disables traffic generation.
  • 3) Reset Source Core — Resets the source core and traffic generator.
  • 4) Reset Sink Core — Resets the sink core and traffic checker.
  • 5) Display Error Details — Displays the error statistics.
  • 6) Toggle Burst/Continuous Mode — Resets the source and sink MACs and switches the traffic generator to generate a burst (multiple burst packet data) or continuous (single continuous data) traffic stream. By default, the design example is set to burst mode. When in continuous mode, the burst count is always 1. Disable the data generator/checker before switching mode to avoid transmission error.
  • 7) Toggle CRC Error Insertion — Turns off or on CRC error injection (for all lanes). By default, the design example has the CRC error injection turned off.
  • 8) Enable Slave Test Mode — This option disables the traffic generator/checker and enables the traffic to flow from sink to source. This option is only available for hardware setup with master and slave configuration using two different development kits.
  • 9) Disable Slave Test Mode — This option disables data flow from sink to source. Select option 1 to enable the data generator and data checker.
