2.3.1.2. E-Tile Hard IP for Ethernet Intel FPGA IP 100GE MAC+PCS with Optional RS-FEC and PTP 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. 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.
    3. Enable IEEE 1588 PTP.
    4. Enable RSFEC to use the RS-FEC feature.
  2. Under the 100GE tab:
    1. 100G as the Ethernet rate.
    2. MAC+1588PTP+PCS+(528,514)RSFEC as the Ethernet IP layer.

In this 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. Waiting for PLL to lock.
  2. Waiting for RX transceiver reset to complete.
  3. Waiting for RX alignment.
  4. Sending 10 packets.
  5. Receiving those packets.
  6. Displaying Testbench complete.

The following sample output illustrates a successful simulation test run for a 100GE, MAC+PCS, RS-FEC, PTP IP core variation.
