The second half of this century will remain as the era of proliferation of electronic computers. They did exist before, but they were mechanical. During next century they may perform other mutations to become optical or molecular or even biological. Actually, all these aspects are only fancy dresses put on mathematical machines. This was always recognized to be true in the domain of software, where "machine" or "high level" languages are more or less rigourous, but immaterial, variations of the universaly accepted mathematical language aimed at specifying elementary operations, functions, algorithms and processes. But even a mathematical machine needs a physical support, and this is what har...
Languages for precisely describing the behavior of computers have been studied since the conception of the computer itself. As the computer industry has grown, so has the need to exchange information about computers. Computer Hardware Description Languages (CHDL) are required to: - provide specifications and detailed implementation for a growing menu of sophisticated design automation tools, including synthesis, verification, simulation, analysis, optimization, placement, wiring and testing - communicate requirements and capabilities between suppliers and users of computer components and subsystems - facilitate the transfer of new methods and results within the university and industrial research community. As reflected in this book, there is an increased emphasis on applications and resulting requirements that are placed on CHDLs. In the field of synthesis, a major application area, there is today a focus on high-level synthesis and synthesis under design constraints. In the area of design correctness, research has shifted away from simulation to formal verification techniques such as temporal logic.

The topic areas presented within this volume focus on design environments and the applications of hardware description and modelling – including simulation, verification by correctness proofs, synthesis and test. The strong relationship between the topics of CHDL'91 and the work around the use and re-standardization of the VHDL language is also explored. The quality of this proceedings, and its significance to the academic and professional worlds is assured by the excellent technical programme here compiled.
Hardware description languages (HDLs) have established themselves as one of the principal means of designing electronic systems. The interest in and usage of HDLs continues to spread rapidly, driven by the increasing complexity of systems, the growth of HDL-driven synthesis, the research on formal design methods and many other related advances.This research-oriented publication aims to make a strong contribution to further developments in the field. The following topics are explored in depth: BDD-based system design and analysis; system level formal verification; formal reasoning on hardware; languages for protocol specification; VHDL; HDL-based design methods; high level synthesis; and text/graphical HDLs. There are short papers covering advanced design capture and recent work in high level synthesis and formal verification. In addition, several invited presentations on key issues discuss and summarize recent advances in real time system design, automatic verification of sequential circuits and languages for protocol specification.
A unique guide to using both modeling and simulation in digital systems design Digital systems design requires rigorous modeling and simulation analysis that eliminates design risks and potential harm to users. Introduction to Digital Systems: Modeling, Synthesis, and Simulation Using VHDL introduces the application of modeling and synthesis in the effective design of digital systems and explains applicable analytical and computational methods. Through step-by-step explanations and numerous examples, the author equips readers with the tools needed to model, synthesize, and simulate digital principles using Very High Speed Integrated Circuit Hardware Description Language (VHDL) programming. E...
The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes ...
VHDL is a comprehensive language that allows a user to deal with design complexity. Design, and the data representing a design, are complex by the very nature of a modern digital system constructed from VLSI chips. VHDL is the first language to allow one to capture all the nuances of that complexity, and to effectively manage the data and the design process. As this book shows, VHDL is not by its nature a complex language. In 1980, the U. S. Government launched a very aggressive effort to advance the state-of-the-art in silicon technology. The objective was to significantly enhance operating performance and circuit density for Very Large Scale Integration (VLSI) silicon chips. The U. S. Gove...
