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.
In the 7-Series Block file change the following:
Verilog
.CHANBOND_DONE (chanbond_done),
To:.CHANBOND_DONE (align_status_i),
VHDL:
Change:CHANBOND_DONE => chanbond_done,
To:CHANBOND_DONE => align_status_i,
