and try to implement a communication using the HSMC- loobpack adapter on port HSMCA. The protocol I'm using is XAUI. I started with the ALTGX and ALTGX_RECONFIG Megafunctions and a pattern generator in conjunction with a pattern checker. This little testdesign works fine in some cases. Mostly the lanes on the receiver are mixed up compared to the transmitter even though the rx_channelaligned signal is set to '1' from the ALTGX function.

I have not seen any lane assignment errors on this board. Do you mean that the data is scrambled from what you expect?
