µCRL: A Toolset for Analysing Algebraic Specifications

µCRL [13] is a language for specifying and verifying distributed systems in an algebraic fashion. It targets the specification of system behaviour in a process-algebraic style and of data elements in the form of abstract data types. The µCRL toolset [21] (see http://www.cwi.nl/~mcrl) supports the analysis and manipulation of µCRL specifications. A µCRL specification can be automatically transformed into a linear process operator (LPO). All other tools in the µCRL toolset use LPOs as their starting point. The simulator allows the interactive simulation of an LPO. There are a number of tools that allow optimisations on the level of LPOs. The instantiator generates a labelled transition system (LTS) from an LPO (under the condition that it is finite-state), and the resulting LTS can be visualised, analysed and minimised.
