Hi Bob,

That made it working. (it should be "set_global_assignment" and not "set_instance_assignment".

Now I see in the Fitter log:

Info (17952): Global preservation of unused RX channels is enabled. Preserving 72 unused RX channel location(s).

Info (18653): Global preservation of unused TX channels is enabled. Preserving 72 unused TX channel location(s).

Info (17953): Preserved 72 unused RX channel(s).

Info (18654): Preserved 72 unused TX channel(s).

So, problem solved. Thanks!

Regards,

Leon

BTW:

I'm still using Quartus 16.0.0 standard.

(I cannot get the pro version to work; I get the same issue as described here: http://www.alteraforum.com/forum/showthread.php?t=52337&highlight=prime )
