Generation of object-oriented programs from CO-OPN specifications

Stanislav Chachkov

The execution of formal specifications is important for verification, validation and animation purposes. This thesis describes transformation of CO-OPN specifications in executable code. The original goal of this transformation was validation by prototypin ...

Unreliable Failure Detectors via Operational Semantics

Rachele Fuzzati

The concept of unreliable failure detectors for reliable distributed systems was introduced by Chandra and Toueg as a fine-grained means to add weak forms of synchrony into asynchronous systems. Various kinds of such failure detectors have been identified ...

Debugging Temporal Specifications with Concept Analysis

James Richard Larus

Program verification tools (such as model checkers and static analyzers) can find many errors in programs. These tools need formal specifications of correct program behavior, but writing a correct specification is difficult, just as writing a correct progr ...

Towards the Formal Integration of Two Upcoming Standards: IEC61970 and IEC61850

Otto Preiss, Christian Frei, Tatjana Kostic

AbstractThe constant demand for a better integration of utility applications and systems provokes the question on the compatibility of standards that were, and still are, developed for these individual utility disciplines. This paper discusses the need for ...

A Formal Analysis of Syverson`s Rational Exchange Protocol

Jean-Pierre Hubaux, Levente Buttyan, Srdan Capkun

In this paper, we provide a formal analysis of a rational exchange protocol proposed by Syverson. A rational exchange protocol guarantees that misbehavior cannot generate benefits, and is therefore discouraged. The analysis is performed using our formal mo ...

From Formal Specifications to Ready-to-Use Software Components: The Concurrent Object-Oriented Petri Net Approach

Stanislav Chachkov

CO-OPN (Concurrent Object Oriented Petri Net) is a formal specification language for modelling distributed systems; it is based on coordinated algebraic Petri nets. In this paper we describe a method for generating an executable prototype from a CO-OPN spe ...

From an Abstract Object-Oriented Model to a Ready-to-Use Embedded System Controller

Stanislav Chachkov

We present an example of a construction of an embedded software system-a controller-from the formal specification to executable code. The CO-OPN (Concurrent Object Oriented Petri Net) formal specification language is used for modelling the controller and t ...

The TL Compiler

This paper describes a method of compiling specification properties into automata or test oracles which allow testing of any proposed implementation. It also shows how to interpret the automata's status during testing. The method addresses verification of ...

Stepwise refinement of formal specifications based on logical formulae

One of the steps making it possible to increase the quality and the reliability of the software executing on distributed systems consists of the use of methods of software engineering that are known as formal. The majority of the formal methods currently e ...
