We report on the analysis of gen_server, a popular Erlang library to build client-server applications. Our analysis uses a tool based on choreographic models. We discuss how, once the library has been modelled in terms of communicating finite state machines, an automated analysis can be used to detect potential communication errors. The results of our analysis suggest how to properly use gen_server...

The Z notation is a language that can be used for writing formal specifications of a system since it is based on mathematical notation and logic. However, there is less tool support for this language that one might wish for. In this paper, Z2SAL, a translator for Z which translates the Z notation into a SAL input language, is explored. The generated SAL file can be used further by an existing model...
The ability to reverse-engineer models of software behaviour is valuable for a wide range of software maintenance, validation and verification tasks. Current reverse-engineering techniques focus either on control-specific behaviour (e.g. in the form of Finite State Machines), or data-specific behaviour (e.g. as pre/post-conditions or invariants). However, typical software behaviour is usually a product...
