ProB is a flexible and extensible validation tool for high-level specification formalisms.
ProB supports

- multiple languages: B, Z, CSP, Event-B, Promela, dSL, ...
- and multiple validation techniques : animation, model checking, ...

Below we present a gentle introduction to ProB focusing on classical B (but many of the commands are also applicable to the other formalisms such as CSP, Event-B and Z).

- First steps in model checking
- Complete model checking
- Understanding the ProB Setup Phases
- Tutorial Troubleshooting the Setup
- Tutorial Understanding the Complexity of B Animation
- Tutorial Understanding ProB's Constraint Solver
- Tutorial Understanding the Complexity of B Model Checking
