V TS-based Specification and Verification of Behavioral Properties of AADL Models
Daniel Monteverde, Alfredo Olivero, Sergio Yovine, Victor A. Braberman · 2008
AADL is an aerospace standard for model-driven design of complex real-time embedded systems. Currently, behavioral properties of AADL models can be specified inside the system description using AADL concepts or outside it using external textual languages, and verified using schedulability analysis or (Time Petri Net-based) model-checking tools. This paper (1) proposes Visual Timed Scenarios (VTS) as a graphical property specification language for AADL, and (2) devises an effective translation from VTS to Time Petri Nets (TPN) which enables modelchecking properties expressed in VTS over AADL models using TPN-based tools integrated into AADL-compliant IDEs (e.g., TOPCASED).
