2.5.2.2. TX Multi-Lane Bonding and RX Multi-Lane Deskew Alignment State Machine

The Interlaken configuration sets the enhanced PCS TX and RX FIFOs in Interlaken elastic buffer mode. In this mode of operation, TX and RX FIFO control and status port signals are provided to the FPGA fabric. Connect these signals to the MAC layer as required by the protocol. Based on these FIFO status and control signals, you can implement the multi-lane deskew alignment state machine in the FPGA fabric to control the transceiver RX FIFO block.

Note: You must also implement the soft bonding logic to control the transceiver TX FIFO block.
