Chat2Code: A Chatbot for Model Specification and Code Generation, The Case of Smart Contracts

The potential of automatic code generation through Model-Driven Engineering (MDE) frameworks has yet to be realized. Beyond their ability to help software professionals write more accurate, reusable code, MDE frameworks could make programming accessible fo ...

Verification of Software Network Functions with No Verification Expertise

Arseniy Zaostrovnykh

Software network functions (NFs), such as a network address translator, load balancer, or proxy, promise to bring flexibility and rapid innovation to computer networks and to reduce operational costs. However, continuous updates and flexibility typically c ...

Type Soundness Proofs with Definitional Interpreters

Nada Amin, Tiark Rompf

While type soundness proofs are taught in every graduate PL class, the gap between realistic languages and what is accessible to formal proofs is large. In the case of Scala, it has been shown that its formal model, the Dependent Object Types (DOT) calculu ...

Synthesizing efficient systems in probabilistic environments

Barbara Jobstmann, David Parker

We present a formalism, algorithms and tools to synthesise reactive systems that behave efficiently, i.e., which achieve an optimal trade-off between a given cost and reward model. Synthesis aims to automatically generate a program from a specification. Mo ...

Modelling Architecture Styles

Anastasia Mavridou

Software systems tend to increase over time in size and complexity. Their development usually spans a long period of time and often results in systems that are hard to understand, debug and maintain. Architectures are common means for organising coordinati ...

Animation-Based Service Specification, Verification and Validation

Biljana Bajic-Bizumic

[Context] With the expansion of services and service science, service systems have become an important abstraction for the service revolution. Service is defined as the application of resources (including competences, skills, and knowledge) to make changes ...

Configuration Logics: Modelling Architecture Styles

Simon Bliudze, Joseph Sifakis, Anastasia Mavridou, Eduard Baranov

We study a framework for the specification of architecture styles as families of architectures involving a common set of types of components and coordination mechanisms. The framework combines two logics: 1) interaction logics for the specification of arch ...

Synthesizing robust systems

Barbara Jobstmann

Systems should not only be correct but also robust in the sense that they behave reasonably in unexpected situations. This article addresses synthesis of robust reactive systems from temporal specifications. Existing methods allow arbitrary behavior if ass ...

Methods to explore design space for MPEG RMC codec specifications

Marco Mattavelli, Richard Thavot, Ghislain Roquier, Endri Bezati, Abdallah Alaaeldin Abdelaziz Elguindy, Simone Casale Brunet

The recent MPEG Reconfigurable Media Coding (RMC) standard aims at defining media processing specifications (e.g. video codecs) in a form that abstracts from the implementation platform, but at the same time is an appropriate starting point for implementat ...

Formalizing and verifying transactional memories

Vasu Singh

Transactional memory (TM) has shown potential to simplify the task of writing concurrent programs. TM shifts the burden of managing concurrency from the programmer to the TM algorithm. The correctness of TM algorithms is generally proved manually. The goal ...

Analog property checkers: a DDR2 case study

Dejan Nickovic

The formal specification component of verification can be exported to simulation through the idea of property checkers. The essence of this approach is the automatic construction of an observer from the specification in the form of a program that can be in ...

Formal semantics for refinement verification of entreprise models

Irina Rychkova

In this dissertation we investigate how Business/IT alignment in enterprise models can be enhanced by using a software engineering stepwise refinement paradigm. To have an IT system that supports an enterprise and meets the enterprise business needs, manag ...

Declarative Specification and Alignment Verification of Services in ITIL

Alain Wegmann, Gil Regev, Irina Rychkova

IT organizations that wish to implement the best practices recommended by the IT Infrastructure Library (ITIL) need to specify the level of service provided to their customers. The implemented service needs to comply with this specification. We propose a m ...

Visual contracts (VCs) : enriching graphical systemic models to support diagrammatic reasoning in system design

José Diego de la Cruz Garcia

Model-Driven Engineering (MDE) harbors the promise of developing software-based systems with little or no coding. Instead of coding, it is envisioned that software engineers build models that are automatically translated into code. The modeling notation of ...

Refinement Propagation. Towards Automated Construction of Visual Specifications

Alain Wegmann, Irina Rychkova

Creation and transformation of visual specifications is driven by modeler’s design decisions. After a design decision has been made, the modeler needs to adjust the specification to maintain its correctness. The number of adjustments might make the design ...

Validation of Visual Contracts for Services

Alain Wegmann, José Diego de la Cruz Garcia, Lam Son Lê

Visual modeling languages have specialized diagrams to represent behavior and concepts. This diagram specialization has drawbacks like the dif-ficulty to represent the effects of actions. We claim that visual contracts can de-scribe actions in a more compl ...
