VHDL is a hardware language that is incorporated in the development of digital systems at several abstraction stages. The dynamic characteristics of this language allow modelling designs that are highly intricate in nature. This book is aimed at providing the readers with an introduction to the subject; the presentation of the book is simple and focuses only on the key features of VHDL. This book is highly recommended for individuals who desire to tap into this highly powerful language, VHDL.

View larger. Additional order info. The aim of this book continues to be the introduction of the VHDL language to the reader at the beginner's level. VHDL is a large and verbose language with many complex constructs that have complex semantic meanings and is initially difficult to understand the US military requires VHDL for device designs, thus explains its popularity vs. The book presents a subset of VHDL consisting of commonly used features that make it both simple and easy to use.
