Exploring AADL verification tool through model transformation

Kai Hu, Teng Zhang, Zhibin Yang, Wei-Tek Tsai
2015 Journal of systems architecture  
Our main contribution is to formally define the translation rules from an adequate subset of AADL (including thread component, port communication, behavior annex and mode change) into TASM.  ...  Finally, a case study from an actual data processing unit of a satellite is provided to validate the transformation and illustrate the practicality of the approach.  ...  Mode change protocols are used to deal with the condition i when a mode change comes with old tasks still in execution.  ...

How to Make AADL Specification More Precise

M. Benammar, F. Belala
2010 International Journal of Computer Applications  
AADL (Architectural Analysis and Design Language) is a textual and graphical language used to design and analyze software architecture of embedded real time systems.  ...  Besides, RT-Maude system offers a natural support to execute and prototype real-time object-oriented modules formalizing AADL architecture behavior composed of several communicating threads.  ...  A change in mode can change the whole of active components and connections.  ...

Formal Verification of AADL Models by Event-B

Abeer Saeed Abdo Hadad, Chunyan Ma, Adeeb Abdulwakeel Obadi Ahmed
2020 IEEE Access  
Model transformation is commonly applied to provide formal semantics; hence, the AADL model can be verified by a language that supports formal verification in addition to the ability to cover all AADL  ...  To demonstrate the efficacy of our method, we model the AADL of movement authority (MA) control of the Chinese Train Control System, transform the AADL model to Event-B and verify its crucial properties  ...  only present the transformation of the AADL subset in the case study that they used.  ...

Real-Time Model Checking Support for AADL [article]

B Berthomieu, M Filali
2015 arXiv   pre-print
We describe a model-checking toolchain for the behavioral verification of AADL models that takes into account the realtime semantics of the language and that is compatible with the AADL Behavioral Annex  ...  We also describe the experimental results obtained on a significant avionic demonstrator, that models a network protocol in charge of data communications between an airplane and ground stations.  ...  AADL subsets A number of studies have explored how to interpret the AADL standard in a formal setting.  ...

Incremental latency analysis of heterogeneous cyber-physical systems

Julien Delange, Peter H. Feiler
2014 IEEE Real-Time Systems Symposium  
It also helps engineers to select appropriate execution platform components or change the deployment strategy of system functions to ensure that latency requirements will be met when implementing the system  ...  We first capture the system functions, its related latency requirements and validate the end-to-end latency at a high level.  ...  The case-study demonstrates that, changing the scheduling and deployment concerns impact the enforcement of an end-to-end latency.  ...

Formal execution semantics for asynchronous constructs of AADL

Jiale Zhou, Andreas Johnsen, Kristina Lundqvist
2012 Proceedings of the 5th International Workshop on Model Based Architecting and Construction of Embedded Systems - ACES-MB '12  
A small case study is presented as a validation of the usefulness of this work.  ...  The main contribution of this paper is a mapping from a substantial asynchronous subset of AADL into the TASM language, allowing us to perform resource consumption and schedulability analysis of AADL models  ...  Future work on this approach will cover a larger subset of AADL components, such as, additional components, the Behavioral Annex, mode change, data communication, the Error Annex, etc.  ...

Sébastien Gérard, Peter Feiler, Jean-Francois Rolland, Mamoun Filali, Mark-Oliver Reiser, Didier Delanote, Yolande Berbers, Laurent Pautet
2007 ACM SIGBED Review  
The purpose of this workshop was to gather people of both communities from UML (including its domain specific extensions, with a focus on MARTE) and AADL (including its annexes) in order to foster sharing  ...  This paper is the result of discussions and exchanges that took place within the second edition of the workshop "UML&AADL" (http://www.artist-embedded.org/artist/Topics.html) thatwas hold in 2007 in Auckland  ...  The later protocol is equivalent to sending a message to an event data port. However, attaching one of these protocols to a subprogram makes easier future changes in the protocol.  ...
