Figure 39. Connection Guidelines for an Interlaken PHY Design
This figure shows the connection of all these blocks in the Interlaken PHY design example available on the Intel
FPGA Wiki website.
For the blue blocks, Intel provides an IP core. The gray blocks use the TX soft bonding logic that is included in
the design example. The white blocks are your test logic or MAC layer logic.
