Document Table of Contents 10GE/25GE MAC+PCS with RS-FEC and PTP Hardware Dynamic Reconfiguration Design Example Components

The 10GE/25GE hardware dynamic reconfiguration 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® -MM address decoder to decode reconfiguration address space for MAC, transceiver, and RS-FEC modules during reconfiguration accesses.
  • Nios® II System that communicates with the Nios® II Software Build Tools (SBT) for Eclipse. You communicate with the client logic and E-tile Ethernet IP for Intel Agilex FPGA through the tool.
  • IO PLL to provide datapath clocks 62.5 MHz and 125 MHz as required by the Triple-Speed Ethernet Intel FPGA IP.
  • ToD master module to provide a continuous flow of current time-of-day information to Triple-Speed Ethernet Intel FPGA IP.
By default, the hardware test run uses the internal serial loopback mode. The following sample outputs illustrate a successful hardware test run for a 25GE, MAC+PCS, RS-FEC, with PTP IP core variation. The hardware test uses this user control GUI to switch to any supported mode.

             Dynamic Reconfiguration Hardware Test

By default, the starting mode is 25G_PTP_FEC.
      Please choose one of Dynamic reconfiguration:
    0) 25G_PTP_FEC    -> 25G_PTP_noFEC -> 10G_PTP -> 25G_PTP_noFEC -> 25G_PTP_FEC -> 10G_PTP -> 25G_PTP_FEC
    1) 25G_PTP_FEC    -> 25G_PTP_noFEC
    2) 25G_PTP_noFEC  -> 25G_PTP_FEC
    3) 25G_PTP_FEC    -> 10G_PTP
    4) 10G_PTP        -> 25G_PTP_FEC
    5) 25G_PTP_noFEC  -> 10G_PTP
    6) 10G_PTP        -> 25G_PTP_noFEC
    9) Terminate test
       If you terminate test halfway, you must reload the .sof file before retrigger the hardware test.
