Guenter and Steven,

I will move the watchdog monitor to a separated thread, as it will require
further discussions specific to it, mainly to get feedback from watchdog
maintainers.

Anyways, I am adding additional information for the sample monitors based on our
discussions here.

They are:

I added documentation about the automata format and the translation between
the formal <-> dot -> C.

I am adding the .dot file to the tools/verification/models/ so that one can get
the .dot file and convert it to other formats, like, a png file. This
will make it easy to read the automata model.

I am adding a .rst documentation for each model, including details about it.

I will send the v5 of RV without the safe_wtd monitor and then start a new
one about the watchdog later, after getting the RV interface series ready.
