Figure 9-2: Swapped Lane Order

Lane 0

Lane N
Two parameters determine lane order:
SWAP_TX_LANES
SWAP_RX_LANES
When a parameter is set to 0, the 100G Interlaken IP core implements the Straight Lane order. When a
parameter is set to 1, the 100G Interlaken IP core implements the Swapped Lane order. The TX and RX
parameters are independent and can be set separately.
To conform with the Interlaken specification, the default value of SWAP_TX_LANES and SWAP_RX_LANES is
1.
Note:
Running traffic with incompatible lane swapping configuration results in CRC24 errors and
incorrect data at the receiver.

Modifying Hidden Parameter Values
To modify the value of a hidden parameter, you must edit one or more generated files. Every time you
regenerate the 100G Interlaken IP core, the files are overwritten and you must edit them again.
Table 9-1: Files to Edit to Modify the Value of a Hidden Parameter
In each entry, the first file controls the RTL parameter value for synthesis, and the second file controls the RTL
parameter value for simulation.
