2.9.6. PMA Direct Mode

The E-Tile Hard IP for Ethernet Intel FPGA IP provides an option to switch from 10G/25G MAC+PCS variant to use PMA only mode during run-time. In this mode, only the reconfiguration and PMA interfaces are enabled. The MAC interface to user logic connection is disabled. The additional interface when you enabled this mode are:
  • i_sl_tx_pma[ch-1:0]
  • o_sl_rx_pma[ch-1:0]

Enable the Include alternate ports in the parameter editor to expose the PMA direct signals. Set tx_ehip_mode[2:0] of register Configuration Fields for TX PLD (address 0x350) to 3'h7 to enable the PMA direct mode. This feature is supported only in 100GE or 1 to 4 10GE/25GE with optional RSFEC and 1588 PTP variant.
