Covergroups not in the DV plan

In pull-request #2380 there was a question regarding some new cross-coverage bins. Although these bins look good, I am worried about two things:

  1. They are not part of any DV plan.
  2. There are a lot of cross-coverage bins which will be very difficult to hit.

My concern is that we now have a situation where the functional coverage score will be decreased and much effort will be needed to fill the new holes. Before we do that, let's:

  • review the coverage to ensure we need it.
  • update the DV plan accordingly.

Covergroups links have been added in #2417, and after the last round of updates and reviews in #2455, I think you could have a look and decide if this issue can be closed.
