Note: The H-Tile Hard IP for Ethernet Intel FPGA IP provides preliminary support for the OTN feature. For further inquiries, contact your nearest Intel sales representative or file an Intel Premier Support (IPS) case on https://www.intel.com/content/www/us/en/programmable/my-intel/mal-home.html.

The testbench sends traffic through the IP core with OTN mode, exercising the transmit and receive PCS66 interfaces using a separate H-Tile Hard IP for Ethernet Intel FPGA MAC as a stimulus generator.

The simulation design example instantiates a main ATX PLL for transceiver channel 0 and 1, and a clock buffer for channel 2 and 3.

The testbench in this design example performs the following:

  1. The client logic resets both the IP cores.
  2. The stimulus client logic waits for the stimulus RX datapath and OTN RX datapath to align.
  3. Once alignment is complete, the stimulus client logic transmits a series of packets to the OTN IP core.
  4. The OTN IP core receives the series of packets and transmits back to the stimulus MAC IP core.
  5. The stimulus client logic then checks the number of packets received and verifies that the packets have no errors.
The following sample output illustrates a successful simulation test run for a 100 Gbps OTN IP core variation. Times are in picoseconds.
