2.15. Auto-Negotiation and Link Training Interface

To enable the auto-negotiation and link training interface, you specify a virtual link at a top-level output port. The port is only available when you turn on the Enable auto-negotiation and link training parameter in the F-Tile Ethernet Multirate Altera FPGA IP parameter editor.

During the compilation, the Quartus® Prime software automatically connects the F-Tile Ethernet Multirate Altera FPGA IP design with the F-Tile Auto-Negotiation and Link Training Altera FPGA IP.
Table 66.  Signals of the Auto-Negotiation and Link Training Interface

For signals description, refer to the F-Tile Ethernet Intel FPGA Hard IP User Guide.
Number of Lanes Signal Name
1, 2, 4, or 8 o_anlt_link[LANE_NUM-1:0]

where LANE_NUM is the maximum number of lanes supported in a reconfiguration group

Auto-Negotiation and Link Training Dynamic Reconfiguration Solution for Multirate IP

The following diagram shows an example design with a 1x100G-4 Base profile. In this setup, the AN/LT IP communicates with the User Logic through the port_state wire, alongside the host AVMM bus. The AN/LT IP is consistently linked to port 0 of the MRIP via the anlt_link conduit. Notably, there is no direct connection between the dynamic reconfiguration IP and the AN/LT IP.
