2.2.1.4. 10GE/25GE Custom PCS 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. Custom PCS with optional RSFEC as the core variant.
    2. Enable RSFEC to use the RS-FEC feature.
  2. Under the Custom PCS Channel(s) tab:
    1. PCS+RSFEC as the custom PCS mode.
Figure 9. Simulation Block Diagram for E-tile Ethernet IP for Intel Agilex FPGA 10GE/25GE Custom PCS with Optional RS-FEC Design Example

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

The successful test run displays output confirming the following behavior:

  1. Wait for PLL to lock.
  2. Wait for RX transceiver reset to complete.
  3. Wait for RX alignment.
  4. Send three sets of packet.
  5. Receive and verify the packets.
  6. Displaying Testbench complete.

The following sample output illustrates a successful simulation test run for a 10GE, custom PCS, RS-FEC IP core variation.
