Out of sheer curiosity: What are you using the coverage data of these
register definitions for? When I looked into coverage analysis the
resulting data seemed rather useless to me, since the important thing
is how well we cover the entire dynamic state space of the hw+sw (e.g.
crap left behind by the bios ...) and coverage seemed to be a poor
proxy for that. Hence why I wonder what you're doing with this data
