Automatic Unbounded Verification of Alloy Specifications with Prover9 [article]

Nuno Macedo, Alcino Cunha
2012 arXiv   pre-print
In this paper we propose a translation from Alloy specifications to fork algebras (an extension of relation algebras with the same expressive power as relational logic) which enables their unbounded verification  ...  This translation covers not only logic assertions, but also the structural aspects (namely type declarations), and was successfully implemented and applied to several examples.  ...  The translation is thus defined by: translate * many(aggregate ⊲ definitions ⊲ uniform * ) Translating Alloy declarations to FA Besides translating Alloy formulas to FA we also need to express in this  ...

Alloy as a Refactoring Checker?

H.-Christian Estler, Heike Wehrheim
2008 Electronical Notes in Theoretical Computer Science  
We will examine how a constraint solver (the Alloy Analyzer) can be used to automatically check if refactorings, applied to a formal specification (written in Z), meet this requirement.  ...  Refactorings are systematic changes made to programs, models or specifications in order to improve their structure without changing the externally observable behaviour.  ...  Translation of a Z state schema into Alloy describe them.  ...

The integrated high level specification language, OZTA, is a combination of Object-Z (OZ) and Timed Automata (TA).  ...  HighSpec supports editing, type-checking as well as projecting OZTA models into TA models and Alloy Models so that TA model checkers-UPPAAL and the Alloy Analyzer can be utilized for verification.  ...  Acknowledgements We would like to thank Chen Qian, and He Kang for their part of work on the coding of HighSpec.  ...

Agile validation of model transformations using compound F-Alloy specifications

Loïc Gammaitoni, Pierre Kelsen, Qin Ma
2018 Science of Computer Programming  
The relational logic based specification language Alloy and its accompanying tool the Alloy Analyzer have been used in the past to validate properties of model transformations.  ...  To tackle the performance and scalability limitations, in previous work, we proposed an Alloy-based Domain Specific Language (DSL), called F-Alloy, that is tailored for model transformation specifications  ...  The semantics of F-Alloy is defined by a translation from F-modules to plain Alloy modules.  ...

An Equational Calculus for Alloy [chapter]

Marcelo F. Frias, Carlos G. López Pombo, Nazareno M. Aguirre
2004 Lecture Notes in Computer Science  
In this paper we show that, by translating Alloy formulas to formulas in the language of fork algebras, we obtain a complete, equational, and purely relational calculus for Alloy.  ...  It presents the translation of Alloy formulas to fork algebra equations, and a theorem that shows that the translation indeed captures the meaning of Alloy formulas.  ...  terms and their translation, and allows us to assess that the translation is sound in the sense that it captures the semantics of Alloy terms.  ...

During the compression tests of a semisolid Al-10mass%Cu alloy with the equiaxed grain structure, translation and rotation of solid grains rather than the plastic deformation played a dominant role in  ...  As the compression proceeded, both translation/ rotation and the plastic deformation of solid grains occurred owing to an increase in physical contact between solid grains.  ...  We are thankful to the members in the research group of "3D/4D analysis for casting defects and segregation during solidification" in the Iron and Steel Institute of Japan for their fruitful discussion  ...

Using the Alloy Analyzer to Verify Data Refinement in Z

Christie Bolton
2005 Electronical Notes in Theoretical Computer Science  
The soundness and joint completeness of the simulation rules for Z have already been established: here we translate them to Alloy.  ...  We then show how data types expressed in Z can also be translated to Alloy, before presenting the assertions necessary for the Alloy Analyzer to identify the retrieve relation and hence verify refinement  ...  by the ease of translation of both data types and simulation rules from Z to Alloy.  ...
