Alignment with user defined comma

Hello!

I need to use user defined comma value for data alignment (the value is "fb"). After data is already aligned, i connect ENPCOMMAALIGN and ENMCOMMAALIGN to 0. But at the moment my channel alignment sequence is changed to usual data, the alignment is lost. I think, it is because there are bytes, equal to comma in data stream... How can I solve this problem?

When I were using a valid comma value K28.5, there was not such kind of problem.

 

I use 7 series transceivers wizard 3.6.

Is 8B10B enabled in your channel or have you switched to raw data?  Your scheme could work with raw data but in either case you have to make sure there is no FB in the datastream either aligned or misaligned.  If you are using 8B10B you need to make sure you specified the characters properly.  It can be confusing so read that section of the UG carefully.  Make sure your scheme works in simulation.  Simulation will be the best platform for debug.
