Formal Systems (Europe) Ltd


We produce the FDR refinement checker, an advanced verification tool for Communicating Sequential Processes (CSP).


FDR3 is a refinement checker for the CSP process algebra produced by the University of Oxford. It is capable of verifying complex properties of systems expressed in CSP, including various safety and liveness properties. FDR has previously been used to verify communications protocols, real-time processors, avionics systems, and complex embedded software systems
