How to constraint variables with randc.(random-cyclic)?Am unable to get proper behavior of randc

In reply to Rao.Bee:

I do not understand that the loop in the sequence should have any influence on the protocol. The protocol behavior is only definde by the driver.
BTW why do you ues the randc declaration? It should also work with a simple rand declaration.
The uniqie does nor solve your issue. Because you are egnerating in your sequence only 1 seq_item. In any case this is unique.
