Fault tollerant state machine problems

I have been doing some experiments on using fault tollerant state machine coding schemes for use in a radiation enviroment, this means defining the state coding for the states and forcing quartus to...

I think, the property "fault tolerant" needs explanation. The most basic kind of fault tolerance is to prevent locking in illegal states, but I don't see, that it's achieved by your coding scheme. Generally the Altera "safe state machine" feature should be considered.

The shown snippet itself is inplausible, it has 31 states in the enumeration but less codings.
