4.3.3.1. 25GE MAC+PCS with RS-FEC and PTP to CPRI Hardware Dynamic Reconfiguration Design Example Components

The 25G Ethernet to CPRI hardware dynamic reconfiguration design example includes the following components:
  • E-tile Ethernet IP for Intel Agilex FPGA core.
  • Client 10G/25G logic that coordinates the programming of the IP core and packet generation.
  • Client XGMII Pattern Generator and Checker that coordinates the programming of the IP core and packet generation.
  • Client 8B/10B Pattern Generator and Checker that coordinates the programming of the IP core and packet generation.
  • Round trip counter to measure the total round trip delay value via the DUT.
  • IO PLL to provide sampling clock, 250 MHz for DUT and the Round trip counter.
  • 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.

When switching from Ethernet to CPRI protocol mode, the CPRI PHY Soft wrapper module reads the TX and RX datapath latency and Round trip counter values and displays them in the dynamic reconfiguration hardware test. For more information about CPRI PHY registers, refer to the E-tile Hard IP User Guide: E-Tile CPRI PHY Intel FPGA IP section.

The following sample outputs illustrate a successful hardware test run for a 25GE, MAC+PCS, RS-FEC, with PTP IP core variation:
