* Properties
Properties are specified in PCTL, with no nested P operators, i.e. essentially we allow unbounded or time-bounded reachability properties: properties of the form Pmin=?[F...], Pmax=?[F...], Pmin=?[F<=T...] or Pmax=?[F<=T...]. See the .pctl files included with the examples for some sample properties. For digital clocks, a few less restrictions are in place, e.g. until formulae are allowed, as are arithmetic expression such as 1-Pmin=?[F...].
