ProB

ProB is a software tool used for analyzing and verifying models written in formal specification languages like B, Event-B, and Pact. It helps developers check whether their systems behave correctly by exploring all possible states and sequences of actions. By doing so, ProB can detect errors or inconsistencies early in the design process, ensuring system reliability and correctness. Commonly used in software and hardware development, it provides visualizations and validation features that make complex models more understandable and testable, ultimately aiding in building safer, more dependable systems.
