4.5.3.1. 100GE MAC+PCS with Optional RS-FEC Dynamic Reconfiguration Simulation Design Example

The simulation block diagram below is generated using the following settings in the IP parameter editor:
  1. 100G Ethernet as DR Protocol.
  2. Under the 100G Ethernet Protocol tab:
    1. 100G Ethernet MAC+PCS RS-FEC as DR Design.
    2. Internal as DR Controller Location.
    3. Stratix 10 E-Tile TX Transceiver Signal Integrity Development Kit as the target development kit.

Refer to the simulation instructions content in the Simulating the E-Tile Hard IP for Ethernet Intel FPGA IP Design Example Testbench section. The steps are applicable for 100G Ethernet MAC+PCS with optional RS-FEC variant.

Figure 51. Simulation Block Diagram for 100GE MAC+PCS with Optional RS-FEC E-Tile Dynamic Reconfiguration 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.

In order to run simulation with the IEEE Ethernet standard specified interval, refer to Non-PTP 10GE/25GE MAC+PCS with Optional RS-FEC Simulation Design Example for more information.

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.
  4. The client logic receives the same series of packets through RX MAC interface.
  5. The client logic then checks the number of packets received and verify that the data matches with the transmitted packets.
  6. Displaying Testbench complete.

The following sample output illustrates a portion of successful simulation test run for a 100GE, MAC+PCS without RS-FEC IP core variation.
