PRISM is a tool for formally verifying the correctness of probabilistic systems.

PRISM is a software tool for modelling and studying the behaviour of real-life systems whose behaviour exhibits unpredictability or randomness. It can be used to analyse everything from the reliability of distributed file systems, to the performance of a Bluetooth-enabled wireless device, to the safety of a car's airbag control system. PRISM has been used by researchers worldwide in fields as diverse as quantum cryptography, systems biology, computer security and robotics. Development of PRISM is based at the University of Birmingham and the University of Oxford, UK, but we have contributors worldwide. It has been under development for over 10 years and contains about 200K lines of code in total. The software is coded primarily in Java, including a graphical user interface written in Swing, but with various underlying libraries written in C/C++.
