From AADL Model to LNT Specification

The verification of distributed real-time systems designed by architectural languages such as AADL (Architecture Analysis and Design Language) is a research challenge. These systems are often used in safety- critical domains where one mistake can result in physical damages and even life loss. In such domains, formal methods are a suitable solution for rigorous analysis. This paper studies the formal verification of distributed real-time systems modelled with AADL. We transform AADL model to another specification formalism enabling the verification. We choose LNT language which is an input to CADP toolbox for formal analysis. Then, we illustrate our approach with the ”Flight Control System” case study
