Description

Currently by default the links are configured as bidirectional.

In some applications only one direction is needed. This would save some resources, especially the BRAMs needed for the second RX FIFO.

The aurora IP supports this mode with the Dataflow-Mode flag.

Implementation would require to pass through a new config flag, change the verilog code to instantiate a send and recv variant and adapt the test example, so it uses only a send or a recv kernel per FPGA.

Research direction

Start by reading the Aurora IP Dataflow-Mode documentation and tracing the existing configuration flag through the Verilog implementation. Then inspect the test example and determine how it should use only a send or receive kernel per FPGA. Done means the new mode is configurable, instantiates the appropriate send/receive variant, and the example reflects unidirectional links.
