Description

Coverage collection is currently limited and should be extended.

Ideally there would be a coverage collector on each major block (TX framer, RX framer, CSRs, loopback, memory map, MAC).
In each one you want to consider three things to cover: configurations, statuses, and events. We should also cover pairs of events e.g. different events occurring under different status/config conditions.

The test suite leaves a couple gaps in the coverage already and I expect improved coverage collection will identify more.

Research direction

Start by reviewing the existing coverage collection in the test suite and the gaps it currently leaves. Check the TX framer, RX framer, CSRs, loopback, memory map, and MAC for coverage of configurations, statuses, events, and relevant event pairs. Done means each major block has the intended collectors and the suite reports the added coverage.
