Formal Semantics and Proof Techniques for Optimizing VHDL Models (eBook, PDF)

• Format: PDF

Produktbeschreibung

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.
