I have a vr_ad model set up which has lists of registers of the same kind. The automatic coverage gives coverage on a per-kind basis, so I know that one of the registers has been read/written, and that all of the fields have been accessed, although not in which register. Is there an easy way to extend the coverage so you actually have it on a per-register basis and show that each individual register has been read/written? The only way I can see to do this is to cross the direction field and individual register fields with the list index in an extension to create my own coverage, as the per_instance coverage is already used to create the register coverage by kind.
