In reply to boss8032:
So you’re talking about the VIP exceptions; which are negative scenarios that can potentially fail the design so they should be verified.
I think supporting them depends on the VIP architecture and implementation.
E.g. I worked with a VIP for SerDes product which supports such scenarios using callbacks, so that the user can override the normal operation to perform specific error injection scenario. This requires excluding this “exception” from the VIP normal-operation checks (to not trigger un-wanted VIP errors) and also proper recovery from that exception condition.
