2.3.2.1. 100GE MAC+PCS with Optional RS-FEC and PMA Adaptation Flow Hardware Design Example Components

Figure 18. 100GE MAC+PCS with Optional RS-FEC Hardware Design Example High Level Block Diagram
The E-tile Ethernet IP for Intel Agilex FPGA hardware design example includes the following components:
  • E-tile Ethernet IP for Intel Agilex FPGA core. The IP core consists of 4 channels if you select (528,514) RS-FEC option, and 2 transceiver channels if you select (544,514) RS-FEC option and enabled asynchronous adapter.
  • Client logic that coordinates the programming of the IP core and packet generation.
  • IOPLL to generate a 100 MHz clock from a 50 MHz input clock to the hardware design example.
  • JTAG controller that communicates with the System Console. You communicate with the client logic through the System Console.

The hardware design example uses run_test command to initiate packet transmission from packet generator to the IP core. By default, the internal serial loopback is disabled in this design example. Use the loop_on command to enable the internal serial loopback. When you use the run_test or the run_test_pam4 commands to run the hardware test in the design examples, the script enables internal loopback. When the internal serial loopback is enabled, the IP core receives the packets and transmit to the packet generator. The client logic reads and print out the MAC statistic registers when the packet transmissions are complete.

The following sample output illustrates a successful hardware test run for 100GE, MAC+PCS with (528,514) RS-FEC variation:
