2.3.1.3. E-tile Ethernet IP for Intel Agilex 7 FPGA 100GE PCS Only 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. PCS_Only, PCS+(528,514)RSFEC, or PCS+(544,514)RSFEC as the Ethernet IP layer.
Figure 15. Simulation Block Diagram for E-tile Ethernet IP for Intel Agilex 7 FPGA 100GE PCS Only Design Example

The testbench sends traffic through the IP core, exercising the transmit side and receive side of the IP core.

To speed up simulation, the IP core simulation model sends alignment marker tags at shorter intervals than required by the IEEE Ethernet standard. The standard specifies an alignment marker interval of 16,384 words in each virtual lane. The simulation model with the testbench implements an alignment marker interval of 512 words.

The successful test run displays output confirming the following behavior:

  1. The client logic resets the IP core.
  2. Waits for RX datapath to align.
  3. Once alignment is complete, client logic transmits a series of packets to the IP core through TX MII interface.
  4. A counter drives i_tx_mii_am port with alignment marker insertion requests at the correct intervals.
  5. The client logic receives the same series of packets through RX MII interface.
  6. The client logic then checks the number of packets received.
  7. Displaying Testbench complete.

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