INSTITUT FÜR INFORMATIK Executing Domain-Specific Models in Eclipse

We present a two-level approach to extend the abstract syntax of domain-specific models with concrete semantics in order to execute such models. First, a light-weight execution infrastructure for executable models with a generic user interface allows the tool smith to provide arbitrary execution and visualisation engine implementations for a DSL. Second, as a concrete but nevertheless generic implementation of a simulation engine for behaviour models, we present semantic model specifications and a runtime interfacing to the Ptolemy II tool suite as a formally founded backbone for model execution. We present our approach as an open source extension to Eclipse modelling projects.
