Formal Design of a Modulo-N Counter

We illustrate the use of functional system speci cations and their re nement in the formal development of hardware systems by a small electronic device an asynchronous modulo N counter The development includes modular speci cation re nement and veri cation We start with an intuitive abstract requirements spec i cation and re ne this into a non trivial concrete bit level implementation The re ne...

Counterexample-Guided Control

A major hurdle in the algorithmic veri cation and control of systems is the need to nd suitable abstract models, which omit enough details to overcome the state-explosion problem, but retain enough details to exhibit satisfaction or controllability with respect to the speci cation. The paradigm of counterexample-guided abstraction re nement suggests a fully automatic way of nding suitable abstr...

Top - level Re nement in Processor Veri cation

We provide a framework for the speci cation and veri ca-tion of high-performance processors. As an example, we give a high-levelspeci cation and correctness proof for a processor that uses speculation,register renaming, superscalar out-of-order execution, and resolution ofmemory dependencies. The speci cations of its three concurrently oper-ating units are very general and c...

Preface Antoni Lig ¦

Evaluation, Veri cation, Validation and Re nement have been important issues from the very beginning of the applications of Intelligent systems. These issues were an important research area and engineering aspect in 80' and 90'. A number of conceptual approaches as well as practical tools was developed then. With time, the focus of research in the design of intelligent systems moved away from t...
