2.9.8. Ethernet Adaptation Flow for 10G/25G and 100G/4x25G Dynamic Reconfiguration Design Example
Refer to Loading a PMA Configuration and PMA Registers 0x200 to 0x203 Usage sections in the E-Tile Transceiver PHY User Guide for more details on the adaptation flow and how to get started.
This adaptation flow assumes a valid Ethernet traffic. 10GE/25GE variant uses the external AIB clocking. 100GE/4x25G variant is using a non-external AIB clocking.
- Assert i_sl_tx_rst_n/i_tx_rst_n/soft_tx_rst and i_sl_rx_rst_n/i_rx_rst_n/soft_rx_rst signals.
- Disable the PMA 9.
- Trigger PMA analog reset 10. Don't call the interrupt sequencer.
- Perform dynamic reconfiguration sequence:
- Switch reference clock.
- Change reference clock ratio.
- Apply RX phase slip.
- Reconfigure AIB, EHIP, PCS, and enable/disable RS-FEC registers.
- In 100GE/4x25GE variants, perform the dynamic reconfiguration reset. Dynamic Reconfiguration requires a staggered reset. For more information, refer to the reset sequence information in the E-Tile Hard IP Stratix® 10 Design Examples User Guide: Ethernet, CPRI PHY, and Dynamic Reconfiguration.
- Enable the PMA9.
- Deassert the i_sl_tx_rst_n/i_tx_rst_n/soft_tx_rst signal.
- If using a PMA configuration, load the PMA configuration using control status registers (CSR). This is loaded to the registers using PMA registers 0x200 to 0x203 11.
- Write 0x40143 = 0x80.
- Read 0x40144[0] until it changes to 1.
- Enable internal serial loopback 12 and run initial adaptation. Verify that the initial adaptation status is complete using interrupt code 0x0126 and data 0x0B00.
- Enable mission mode and disable internal serial loopback (skip this step if using internal serial loopback)12.
- Wait for valid data traffic on RX and then proceed to the next step.
- Run initial adaptation. Verify that the initial adaptation status is complete using interrupt code 0x0126 and data 0x0B00 (skip this step if using internal serial loopback).
- Run continuous adaptation 13.
- Deassert the i_sl_rx_rst_n/i_rx_rst_n/soft_rx_rst signal.
- Optional: Verify that the link status signal rx_aligned transitions high.
- Send packets.

11 Refer to Loading a PMA Configuration and PMA Registers 0x200 to 0x203 Usage sections in the E-Tile Transceiver PHY User Guide.
12 For how to enable and disable internal serial loopback, refer to 0x0008: Internal Serial Loopback and Reverse Parallel Loopback Control section in the E-Tile Transceiver PHY User Guide.
13 During the continuous adaptation, the link partner must keep sending the data. If link goes down, the entire sequence must be repeated.
