Digital Electronics with VHDL provides the fundamentals of digital circuitry; it is designed to be easy to read and to provide all of the information necessary for the motivated reader to understand this new subject matter. The subject matter is introduced using the fixed-function ICs and evolves into CPLDs (Complex Programming Logic Devices) programmed with VHD (VHSIC Hardware Description Language). Basic logic gates are used to perform arithmetic operations; then the book proceeds through sequential logic and memory circuits to interface to modern PCs. For those self-learners needing to understand digital electronics with VHDL programming and the utilization of CPLDs. These include programmers, system analysts, and electronic technicians.
