2.3.1.4. E-tile Ethernet IP for Intel Agilex® 7 FPGA 100GE OTN with Optional RS-FEC Simulation Design Example

The simulation block diagram below is generated using the following settings in the IP parameter editor:
  1. Under the IP tab:
    1. Single 100GE with optional RSFEC or 100GE or 1 to 4 channel 10GE/25GE with optional RSFEC and PTP as the core variant.
    2. 100GE Channel as Active channel(s) at startup if you choose 100GE or 1 to 4 channel 10GE/25GE with optional RSFEC and PTP as the core variant.
  2. Under the 100GE tab:
    1. 100G as the Ethernet rate.
    2. OTN, OTN+(528,514)RSFEC, or OTN+(544,514)RSFEC as the Ethernet IP layer.
Note: The E-tile Ethernet IP for Intel Agilex® 7 FPGA provides support for the OTN feature. For further inquiries, contact your nearest Intel sales representative.
Figure 16. Simulation Block Diagram for E-tile Ethernet IP for Intel Agilex® 7 FPGA 100GE OTN Design Example

The testbench sends traffic through the IP core with OTN mode, exercising the transmit side and receive interface using a separate E-tile Ethernet IP for Intel Agilex® 7 FPGA MAC as a stimulus generator.

The successful test run displays output confirming the following behavior:

  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 verify that the packets have no errors.
  6. Displaying Testbench complete.

The following sample output illustrates a successful simulation test run for a 100GE OTN IP core variation.
