2.3.1.1. Non-PTP E-tile Ethernet IP for Intel Agilex® 7 FPGA 100GE MAC+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. 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.
    3. Enable RSFEC to use the RS-FEC feature.
      Note: The RS-FEC feature is only available when you select 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. MAC+PCS as Select Ethernet IP Layers to use instantiate MAC and PCS layer or MAC+PCS+(528,514)RSFEC/MAC+PCS+(544,514)RSFEC to instantiate MAC and PCS with RS-FEC feature.
  3. Enable asynchronous adapter clocks to use the asynchronous adapter feature.
Figure 13. Simulation Block Diagram for E-tile Ethernet IP for Intel Agilex® 7 FPGA 100GE MAC+PCS with Optional RS-FEC Design Example
Note: If Enable asynchronous adapter clocks is enabled, the o_clk_div66 feeds the i_clk_tx and i_clk_rx clocks.

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.

Perform these steps in order to run simulation with the IEEE Ethernet standard specified interval:
  1. Open <design_example>/ex_<speed>/synth/ex_<speed>.v and disable sim_mode parameter.
  2. Uncommand the following in the file.
    • <example_design_varaition_name>\example_testbench\basic_avl_tb_top.sv
  3. Command in //defparam dut.alt_ehipc3_fm_hard_inst.E100GX4_FEC.altera_xcvr_native_inst.xcvr_native_s10_etile_0_example_design_4ln_ptp.generate_RSFEC_block.inst_ct3_hssi_rsfec.ct3_hssi_rsfec_encrypted_inst.ct1_hssirtl_rsfec_wrap_inst.die_specific_inst.x_rsfec_wrap.LOG2_MRK = 10;

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 successful simulation test run for a 100GE, MAC+PCS with optional RS-FEC IP core variation.
