We present a generic co-simulation approach between discrete-event models, developed in the Event-B formal method, and continuous models, exported via the Functional Mock-up Interface for Co-simulation standard. The concept is implemented into a simulation extension for the Rodin platform, thus leveraging powerful capabilities of refinementbased modelling and deductive verification in Event-B w...

Code generation is a technique for automatically generating implementations from formal specifications. In this paper we describe automatic generation of programs in the objectoriented programming language C++ from formal specifications written in LOTOS. We present its theoretical foundation and report on our experience in implementing a support toolset. A key feature of our tool development is...

UML is considered as the standard for object-oriented modelling language adopted by the Object Management Group. However, UML has been criticized due to the lack of formal semantics and the ambiguity of its models. In other hands, UML models can be mathematically verified and checked by using its equivalent formal representation. So, in this paper, we propose an approach and a tool based on gra...

This chapter contributes to the formal specification of Kermeta, a popular metamodelling framework useful for the design of DSL structure and semantics. The formal specification is tool-/tool syntax independent; it only uses classical mathematical instruments taught in usual computer science courses. This specification serves as a reference specification from which specialised implementation ca...

KeY is a tool that provides facilities for formal specification and verification of programs within a commercial platform for UML based software development. Using the KeY tool, formal methods and object-oriented development techniques are applied in an integrated manner. Formal specification is performed using the Object Constraint Language (OCL), which is part of the UML standard. KeY provide...

This paper describes the use of a formal method to support component-based development in the healthcare domain. The method is based on a commercial tool suite which combines formal modeling, compositional model checking, and code generation. The main approach of the tool suite will be explained and demonstrated from a user point of view. We report about experiences with this approach at the co...

Construction of correctness is an essential issue for the implementation of a reliable software system. Formal methods based verification techniques provide programmers various ways to reason their program correctness through mathematically supported static analysis and dynamic analysis. In this paper, we introduce a tool that converts formal specifications in a subset of Object-Z to skeletal S...

We build an open-source RTL framework, QuteRTL, which can serve as a front-end for research in RTL synthesis and verification. Users can use QuteRTL to read in RTL Verilog designs, obtain CDFGs, generate hierarchical or flattened gate-level netlist, and link to logic synthesis/ optimization tools (e.g. Berkeley ABC). We have tested QuteRTL on various RTL designs and applied formal equivalence c...

This paper discusses our experiences and results in applying functional formal verification (FFV) techniques to the design of the IBM pSeriest microprocessor and communication subsystem. We describe the evolution of FFV deployment across several generations of this product line, including tool and algorithmic improvements, as well as methodological improvements for prioritizing the portions of ...

This paper presents a new tool, named SDL Performance Evaluation Tool (SPEET) 2 , for the performance analysis of formally speciied systems under real{time conditions. SPEET facilitates the simulation and emulation of several formal speciications at the same time. The systems to be simulated, resp. to be emulated, can be triggered by traac load generators and can be interconnected with transmis...
