Do fava beans grow tender or soft when cooked on a soup or stew?

Dried fava beans take a couple of hours to cook, and fresh fava beans cook in 3 - 5 minutes.

And just to distinguish, you have to shell fresh favas and I think we are past the end of the season. For dried I would go so far as to soak them overnight.
