The FSA group is a cluster in the  department of Mathematics and Computer Science of the Eindhoven University of Technology. Research in the FSA group focusses on theories, techniques and tools for modelling and analysing the behaviours of (concurrent) systems.  Among others, we study process algebras, semantics, concurrency theory, model checking, logics, rewriting and satisfiability solving.


Application areas include protocols, hardware designs and industrial control systems. Examples include the verification of the control systems of the four large experiments in the Large Hadron Collider  at CERN; analysis of networks-on-chips;  formalisation of the industrial modelling and code generation language Dezyne; the analysis of the software architecture of the winning Stella Solar Car.


Tools developed by the group include mCRL2 (/ˈmak(ə)r(ə)l 2/ according to someand MaDL. mCRL2 is a process-algebraic language with an award winning tool set for modelling and analysing concurrent systems. MaDL is a language with associated verification techniques for micro-architectures. The techniques focus on scalable liveness verification.
