Featured Extended Team Automata (FETA)
FETA is a formalism to reason about communication safety in families (or software product lines) of teams, which are systems of reactive components that communicate according to specified synchronisation types.
This repository provides a prototype tool to specify and analysis FETA. Currently, it is possible to try the tool online at
To compile and run locally these analysis using a web frontend you need to compile and run the code from a specific branch of the ReoLive repository, available at https://github.com/ReoLanguage/ReoLive/tree/feta-only.
When running the tool you will be able to:
- specify Extended Team Automata (ETA) and Feature Extended Team Automata (FETA);
- Infer how many products of the Featured family exist, how many states, how many transitions, and other properties;
- Visualise the global automaton, both before and after applying the synchronisation policies;
- Visualise the automata of the individual components;
- Generate logical formulas that characterise receptiveness and responsiveness, and their weak counterparts of a single ETA;
- Use mCRL2 model checker to infer whether the ETA is receptive and responsive, producing counter-examples when not.
