Description

When targeting GTX or GTH 7 series Transceivers, the XAUI Core might fail to link up after the link partner is reset or there is a cable re-plug.

In this case, synchronization is achieved on all four lanes, but align_status remains low.

An update is needed to the channel bond monitor block inputs to ensure that a reset is issued if channel bonding is not successful.

Solution

In the 7-Series Block file change the following:

Verilog

.CHANBOND_DONE (chanbond_done),

.CHANBOND_DONE (align_status_i),

VHDL:

CHANBOND_DONE => chanbond_done,

CHANBOND_DONE => align_status_i,
