This paper introduces the artshop model repository framework which, among others, includes methods to analyse the structure and quality of the architecture of model-based software developed with The Mathwork's Matlab-Simulink/Stateflow. The framework supports the import of MATLAB-Simulink/Stateflow models and is able to synchronize imported models with their initial sources. Imported model data can be queried, inspected, analyzed and enriched with meta-information like associations or additional documentation. Analyses provided by artshop include duplicate detection, model slicing, various coupling and cohesion metrics and user-defined conformity checks for MATLAB/Simulink models.
