Abstract

The Temporal Language of Transitions (TLT) is a framework for the design and verification of distributed systems being developed at Siemens. Similar to UNITY and TLA, it is a formalism to model systems and specify their properties. It further includes methods for refinement and composition, used repeatedly in this case study. We were able to specify, verify and simulate a distributed controller that can handle up to eight plates. The correctness proofs for both safety and liveness properties were done automatically using a model checking tool based on BDDs.
