Book Description
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."

Book Description
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.

Book Description
With our ever-increasing reliance on computer technology in every field of modern life, the need for continuously evolving and improving cyber security remains a constant imperative. This book presents the 3 keynote speeches and 10 papers delivered at the 2nd Singapore Cyber Security R&D Conference (SG-CRC 2017), held in Singapore, on 21-22 February 2017. SG-CRC 2017 focuses on the latest research into the techniques and methodologies of cyber security. The goal is to construct systems which are resistant to cyber-attack, enabling the construction of safe execution environments and improving the security of both hardware and software by means of mathematical tools and engineering approaches for the design, verification and monitoring of cyber-physical systems. Covering subjects which range from messaging in the public cloud and the use of scholarly digital libraries as a platform for malware distribution, to low-dimensional bigram analysis for mobile data fragment classification, this book will be of interest to all those whose business it is to improve cyber security.

Book Description
In this fourth book in the CHDL Series, a selection of the best papers presented in FDL'02 is published. System Specification and Design Languages contains outstanding research contributions in the four areas mentioned above. So, The Analog and Mixed-Signal system design contributions cover the new methodological approaches like AMS behavioral specification, mixed-signal modeling and simulation, AMS reuse and MEMs design using the new modeling languages such as VHDL-AMS, Verilog-AMS, Modelica and analog-mixed signal extensions to SystemC. UML is the de-facto standard for SW development covering the early development stages of requirement analysis and system specification. The UML-based system specification and design contributions address latest results on hot-topic areas such as system profiling, performance analysis and UML application to complex, HW/SW embedded systems and SoC design.C/C++-for HW/SW systems design is entering standard industrial design flows. Selected papers cover system modeling, system verification and SW generation. The papers from the Specification Formalisms for Proven design workshop present formal methods for system modeling and design, semantic integrity and formal languages such as ALPHA, HANDLE and B.
