摘要

The verification of High-Integrity Real-Time systems combines heterogeneous concerns: preserving timing constraints, ensuring behavioral invariants, or specific execution patterns. Furthermore, each concern requires specific verification techniques; and combining all these techniques require automation to preserve semantics and consistency. Model-based approaches focus on the definition of representation of a system, and its transformation to equivalent representation for further processing, including verification and are thus good candidates to support such automation. In this paper, we show there is a strong requirement to automatically map high-level models to abstractions that are dedicated to specific analysis techniques taking full advantage of tools. We discuss this requirement on a case study: validating some aspects of AADL models using both coloured and time Petri Nets.
