Model checking CSLTA with Deterministic and Stochastic Petri Nets

CSLTA is a stochastic temporal logic for continuous-time Markov chains (CTMC), that can verify the probability of following paths specified by a Deterministic Timed Automaton (DTA). A DTA expresses both logic and time constraints over a CTMC path, yielding to a very flexible way of describing performance and dependability properties. This paper explores a model checking algorithm for CSLTA based on the translation into a Deterministic and Stochastic Petri Net (DSPN). The algorithm has been implemented in a simple Model Checker prototype, that relies on existing DSPN solvers to do the actual numerical computations.
