The Modest Modeling Tool and Its Implementation

This paper is about the tool-suite Motor that supports the modeling and analysis of Modest specifications. In particular, we discuss its tool architecture, and the implementation details of the tool components that do already exist, in particular, the parser, the SOS implementation, an interactive simulator, and a state-space generator. As the expressiveness of Modest goes beyond existing notations for real-time as well as probabilistic systems, the implementation of these tool components has a non-trivial intrinsic complexity.
