Visualization of behavioral aspects of AADL-models

In the paper, we describe a metamodel to represent dynamics of AADL-models. The metamodel allows to visualize step-by-step a process of models' behavioral aspects analysis. In particular, it essentially helps to debug behavioral specifications. In the paper, we consider examples of the metamodel usage to represent dynamics for the following two aspects of AADL-models: 1) simulation of a modelled system on the basis of a Behavior Annex specification; 2) failure modes and effects analysis on the basis of an Error Model Annex specification. We also present a stepwise visualization tool (engine and applications for both mentioned examples) that is implemented in MASIW framework for design of modern avionics systems.
