Given the diierent perspectives from which a complex software system has to be analyzed, the multiplicity of formalisms is in some sense unavoidable. This poses two important technical challenges: how to rigorously meet the need to interrelate formalisms, and how to reduce the duplication of eeort in tool and speciication building across formalisms. These challenges could be answered by adequat...

This paper describes the K tool, a system for formally defining programming languages. Formal definitions created using the K tool automatically yield an interpreter for the language, as well as program analysis tools such as a state-space explorer. The modularity of K and the design of the tool allow one semantics to be used for several applications.

It is recognised that Formal Methods will play a vital role in ensuring the integrity of computer systems, particularly safety-critical computer systems. Formal refinement is a part of the Formal Methods field that supports the stepwise development of correct computer systems. To apply formal refinement techniques successfully, tool support that is both usable and sound is essential. This paper...

This paper discusses the Intelligent Knowledge Database (IKD) tool generated for formal methods. The knowledge database provides the information regarding the existing formal methods in the area of academia, industry and R&D sectors. The tool provides complete information about the formal methods adopted in the conventional or model-based approach, in the various phases of the software developm...

in recent years, formal methods have been used as an important tool forperformance evaluation and verification of a wide range of systems. in the viewpoints of engineers and practitioners, however, there are still some major difficultiesin using formal methods. in this paper, we introduce a new formal modelinglanguage to fill the gaps between object-oriented programming languages (oopls)used by...
