Description Gerd Behrmann 2006-05-08 19:31:53 CEST
In the attached system, the property E<> not deadlock is satisfied (the initial state is not deadlocked). However, UPPAAL states that this property is not satisfied. The normal case of E<> deadlock or A[] not deadlock is not affected.

Normally, I clasify wrong verification results as critical, however the practical use of such a property is limitted.
