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.

This book was released on 2012-12-06 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written expressly for hardware designers, this book presents a formal model of VHDL clearly specifying both the static and dynamic semantics of VHDL. It provides a mathematical framework for representing VHDL constructs and shows how those constructs can be formally manipulated to reason about VHDL.

This book was released on 2018-11-06 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the first part of the report, we give a detailed description of an operational semantics for a large subset of VHDL, the VHSIC Hardware Description Language. The semantics is written in the functional language Caliban, similar to Haskell, used by the theorem prover Clio. We also describe a translator from VHDL into Caliban semantics and give some examples of its use. In the second part of the report, we describe our experience in using the VHDL semantics to try to verify a large VHDL design. We were not able to complete the verification due to certain complexities of VHDL which we discuss. We propose a VHDL verification method that addresses the problems we encountered but which builds on the operational semantics described in the first part of the report.

Download or read book Functional Semantics for Delta delay VHDL Based on FOCUS written by Max Fuchs and published by . This book was released on 1994 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This tutorial paper gives a functional semantics for delta-delay VHDL, i.e. VHDL restricted to zero-delay signal assignments. In combination with the sequential statements zero-delay signal assignment is sufficient to generate the full algorithmic expressibility of VHDL. The restriction is useful for a formal semantics of VHDL aimed at higher levels of abstraction where real, absolute, and precise timing often is painful if not impossible to prescribe. The approach employs the functional specification methodology FOCUS which is based on the concept of streams and stream-processing functions. It advocates a three-level semantics reflecting VHDL's three syntactic levels of expressions, statements, and processes."
Download or read book Practical Formal Methods for Hardware Design written by Carlos Delgado Kloos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formal methods for hardware design still find limited use in industry. Yet current practice has to change to cope with decreasing design times and increasing quality requirements. This research report presents results from the Esprit project FORMAT (formal methods in hardware verification) which involved the collaboration of the enterprises Siemens, Italtel, Telefonica I+D, TGI, and AHL, the research institute OFFIS, and the universities of Madrid and Passau. The work presented involves advanced specification languages for hardware design that are intuitive to the designer, like timing diagrams and state based languages, as well as their relation to VHDL and formal languages like temporal logic and a process-algebraic calculus. The results of experimental tests of the tools are also presented.
Download or read book VHDL Designer s Reference written by Jean-Michel Bergé and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: too vast, too complex, too grand ... for description. John Wesley Powell-1870 (discovering the Grand Canyon) VHDL is a big world. A beginner can be easily disappointed by the generality of this language. This generality is explained by the large number of domains covered - from specifications to logical simulation or synthesis. To the very beginner, VHDL appears as a "kit". He is quickly aware that his problem may be solved with VHDL, but does not know how. He does not even know how to start. In this state of mind, all the constraints that can be set to his modeling job, by using a subset of the language or a given design methodology, may be seen as a life preserver. The success of the introduction of VHDL in a company depends on solutions to many questions that should be answered months before the first line of code is written: • Why choose VHDL? • Which VHDL tools should be chosen? • Which modeling methodology should be adopted? • How should the VHDL environment be customized? • What are the tricks? Where are the traps? • What are the differences between VHDL and other competing HDLs? Answers to these questions are organized according to different concerns: buying the tools, organizing the environment, and designing. Decisions taken in each of these areas may have many consequences on the way to the acceptance and efficiently use of VHDL in a company.

Download or read book Hardware Description Languages and their Applications written by Carlos Delgado Kloos and published by Springer. This book was released on 2013-06-05 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few decades Computer Hardware Description Languages (CHDLs) have been a rapidly expanding subject area due to a number of factors, including the advancing complexity of digital electronics, the increasing prevalence of generic and programmable components of software-hardware and the migration of VLSI design to high level synthesis based on HDLs. Currently the subject has reached the consolidation phase in which languages and standards are being increasingly used, at the same time as the scope is being broadened to additional application areas. This book presents the latest developments in this area and provides a forum from which readers can learn from the past and look forward to what the future holds.

Download or read book VHDL for Simulation Synthesis and Formal Proofs of Hardware written by Jean Mermet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The success of VHDL since it has been balloted in 1987 as an IEEE standard may look incomprehensible to the large population of hardware designers, who had never heared of Hardware Description Languages before (for at least 90% of them), as well as to the few hundreds of specialists who had been working on these languages for a long time (25 years for some of them). Until 1988, only a very small subset of designers, in a few large companies, were used to describe their designs using a proprietary HDL, or sometimes a HDL inherited from a University when some software environment happened to be developped around it, allowing usability by third parties. A number of benefits were definitely recognized to this practice, such as functional verification of a specification through simulation, first performance evaluation of a tentative design, and sometimes automatic microprogram generation or even automatic high level synthesis. As there was apparently no market for HDL's, the ECAD vendors did not care about them, start-up companies were seldom able to survive in this area, and large users of proprietary tools were spending more and more people and money just to maintain their internal system.
