Unifying Theories of Reactive Design Contracts [article]

Simon Foster, Ana Cavalcanti, Samuel Canham, Jim Woodcock, Frank Zeyda
2019 arXiv   pre-print
In this paper, we describe a unifying theory for reactive design contracts that provides the basis for modelling and verification of reactive systems.  ...  Being based in Unifying Theories of Programming (UTP), our theory can be composed with further computational theories to support semantics for multi-paradigm languages.  ...  We also thank the anonymous reviewers of this article, whose suggestions have greatly improved the presentation of our work.  ...

Mechanical Reasoning about Families of UTP Theories

Frank Zeyda, Ana Cavalcanti
2009 Electronical Notes in Theoretical Computer Science  
In this paper we present a semantic embedding of Hoare and He's Unifying Theories of Programming (UTP) framework into the ProofPower-Z theorem prover; it concisely captures the notion of UTP theory, theory  ...  We support encoding and reasoning about combinations of elements of collections of theory instantiations, as typically found in UTP models of particular specifications and programs.  ...  We would also like to acknowledge EPSRC for funding this work under the "Programming from Control Laws" research grant EP/E025366/1.  ...

Automating Verification of State Machines with Reactive Designs and Isabelle/UTP [article]

Simon Foster, James Baxter, Ana Cavalcanti, Alvaro Miyazawa, Jim Woodcock
2018 arXiv   pre-print
In this paper, we present a verification approach for a diagrammatic state machine language that utilises theorem proving and a denotational semantics based on Unifying Theories of Programming (UTP).  ...  State-machine based notations are ubiquitous in the description of component systems, particularly in the robotic domain.  ...  This work is funded by the EPSRC projects RoboCalc 4 (Grant EP/M025756/1) and CyPhyAssure (Grant EP/S001190/1), and the Royal Academy of Engineering.  ...

Unifying Theories in ProofPower-Z [chapter]

Marcel Oliveira, Ana Cavalcanti, Jim Woodcock
2006 Lecture Notes in Computer Science  
The increasing interest in the combination of different computational paradigms is well represented by Hoare & He in the Unifying Theories of Programming (UTP).  ...  We aim at providing tool support not only for CSP and Circus, but also for further explorations of Hoare & He's unification, and for the mechanisation of languages whose semantics is based on the UTP.  ...  Acknowledgements We thank QinetiQ and the Royal Society for their financial support. The work of Marcel Oliveira is supported by CNPq: grant 551210/2005-2.  ...
