Download or read book Formal Semantics for VHDL written by Carlos Delgado Kloos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is recognized that formal design and verification methods are an important requirement for the attainment of high quality system designs. The field has evolved enormously during the last few years, resulting in the fact that formal design and verification methods are nowadays supported by several tools, both commercial and academic. If different tools and users are to generate and read the same language then it is necessary that the same semantics is assigned by them to all constructs and elements of the language. The current IEEE standard VHDL language reference manual (LRM) tries to define VHDL as well as possible in a descriptive way, explaining the semantics in English. But rigor and clarity are very hard to maintain in a semantics defined in this way, and that has already given rise to many misconceptions and contradictory interpretations. Formal Semantics for VHDL is the first book that puts forward a cohesive set of semantics for the VHDL language. The chapters describe several semantics each based on a different underlying formalism: two of them use Petri nets as target language, and two of them higher order logic. Two use functional concepts, and finally another uses the concept of evolving algebras. Formal Semantics for VHDL is essential reading for researchers in formal methods and can be used as a text for an advanced course on the subject.

Available in PDF, EPUB and Kindle. Book excerpt: L'OBJET DE CETTE THESE EST LA VERIFICATION FORMELLE DES CIRCUITS DIGITAUX DECRITS EN VHDL. NOUS AVONS, EN PREMIER LIEU RESTREINT VHDL POUR LE RENDRE UTILISABLE PAR LES OUTILS DE PREUVE EXISTANTS, EN PROPOSANT UN SOUS-ENSEMBLE, APPELE P-VHDL, AFIN DE DECRIRE LES CIRCUITS COMBINATOIRES ET LES CIRCUITS SEQUENTIELS SYNCHRONES. UN TEL SOUS ENSEMBLE A UNE SEMANTIQUE BEAUCOUP PLUS SIMPLE QUE CELLE DE VHDL COMPLET. EN FAIT, LE RETARD DELTA A ETE REMPLACE PAR UNE SIMPLE FONCTION DE SEQUENCEMENT. ET L'ECHELLE DE TEMPS DEVIENT LA PERIODE DE L'HORLOGE. AINSI, LA MACHINE D'ETAT FINI A PU ETRE UTILISEE COMME MODELE FORMEL POUR LE SOUS-ENSEMBLE. L'EQUIVALENCE ENTRE CE MODELE ET LA SEMANTIQUE DE VHDL A ETE MONTREE SOUS LES RESTRICTIONS SYNTAXIQUES ET SEMANTIQUES IMPOSEES PAR P-VHDL. CE MODELE EST A LA BASE DE L'ECRITURE D'UN COMPILATEUR EN VUE DE LA PREUVE QUI CONSTITUE LE CUR DE L'ENVIRONNEMENT DE VERIFICATION FORMELLE PREVAIL. PUIS NOUS AVONS DEFINI UNE SEMANTIQUE DENOTATIONNELLE POUR P-VHDL. POUR CELA, NOUS AVONS PROPOSE TROIS DOMAINES DIFFERENTS POUR LES TROIS OBJETS PORTEURS DES VALEURS: LES VARIABLES, LES SIGNAUX ET LES REGISTRES. ENSUITE, NOUS AVONS PROPOSE UNE SEMANTIQUE FORMELLE POUR LES PRIMITIVES TEMPORELLES DE VHDL, ET NOUS AVONS PROUVE, PARTIELLEMENT, L'EQUIVALENCE ENTRE CETTE SEMANTIQUE ET LA SEMANTIQUE OPERATIONNELLE INFORMELLE DE VHDL. ENFIN, NOUS AVONS MONTRE COMMENT NOTRE SEMANTIQUE PEUT CONSTITUER UNE BASE DE CONSTRUCTION D'UN SYSTEME DE VERIFICATION TEMPORELLE

Available in PDF, EPUB and Kindle. Book excerpt: A handbook to the Coq software for writing and checking mathematical proofs, with a practical engineering focus. The technology of mechanized program verification can play a supporting role in many kinds of research projects in computer science, and related tools for formal proof-checking are seeing increasing adoption in mathematics and engineering. This book provides an introduction to the Coq software for writing and checking mathematical proofs. It takes a practical engineering focus throughout, emphasizing techniques that will help users to build, understand, and maintain large Coq developments and minimize the cost of code change over time. Two topics, rarely discussed elsewhere, are covered in detail: effective dependently typed programming (making productive use of a feature at the heart of the Coq system) and construction of domain-specific proof tactics. Almost every subject covered is also relevant to interactive computer theorem proving in general, not just program verification, demonstrated through examples of verified programs applied in many different sorts of formalizations. The book develops a unique automated proof style and applies it throughout; even experienced Coq users may benefit from reading about basic Coq concepts from this novel perspective. The book also offers a library of tactics, or programs that find proofs, designed for use with examples in the book. Readers will acquire the necessary skills to reimplement these tactics in other settings by the end of the book. All of the code appearing in the book is freely available online.
