2.3.2.2. 100GE MAC+PCS with Optional RS-FEC and PTP Hardware Design Example

Figure 19. 100GE MAC + PCS with Optional RS-FEC and PTP Hardware Design Examples 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.
  • Client logic that coordinates the programming of the IP core and packet generation.
  • Time-of-day (ToD) module to provide a continuous flow of current time-of-day information to the IP core.
  • PIO block to store RX and TX PTP timestamp for accuracy calculation and to send PTP 2-step timestamp request.
  • Avalon® memory-mapped interface address decoder to decode reconfiguration address space for MAC, transceiver, and RS-FEC modules during reconfiguration accesses.
  • JTAG controller that communicates with the System Console. You communicate with the client logic through the System Console.

The following sample output illustrates a successful hardware test run for a 100GE, MAC+PCS with RS-FEC, non-PTP IP core variation. The test results are located at <design_example_dir>/hardware_test_design/hwtest_ptp/c3_elane_xcvr_loopback_test.log or <design_example_dir>/hardware_test_design/hwtest_ptp/c3_elane_traffic_basic_test.log.
