Abstract

This paper describes a framework currently under development for modelling, simulation, and verification of relay interlocking systems as used by the Danish railways. The framework is centred around a domain-specific language (DSL) for describing such systems, and provides (1) a graphical editor for creating DSL descriptions, (2) a data validator for checking that DSL descriptions follow the structural rules of the domain, (3) a graphical simulator for simulating the dynamic behaviour of relay interlocking systems, and (4) verification support for deriving and verifying safety properties of relay interlocking systems.
