Book 1 - Fundamentals of Digital Logic with VHDL Design


  • Fundamentals of Digital Logic With VHDL Design teaches the basic design techniques for logic circuits.
  • It emphasizes the synthesis of circuits and explains how circuits are implemented in real chips.
  • Fundamental concepts are illustrated by using small examples, which are easy to understand.
  • Then, a modular approach is used to show how larger circuits are designed.
  • VHDL is used to demonstrate how the basic building blocks and larger systems are defined in a hardware description language, producing designs that can be implemented with modern CAD tools.

Devices 1 - 74HC08 / 74HCT08

  • The 74HC/HCT08 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).
  • They are specified in compliance with JEDEC standard no. 7A.
  • The 74HC/HCT08 provide the 2-input AND function.

Application 1 - PLC Controlled Analog Multiplexer

  • Various use of multiplexer with PLC has been introduced.
  • 6 x digital channel and 1 x analog channel used by the PLC to make this multiplexer work.
  • In this example the analog inputs are 4 - 20mA none floating loops.
  • The 1 x analog output to the PLC is 2-10VDC.
  • 74HC/HCT4067 is the 16ch analog multiplexer/demultiplexer circuit used in this example.

Tutorial 2 - Computer Assisted Learning

  • This is a Computer Assisted Learning application to support the first year Digital Logic module from the Electronic Engineering course.
  • Queries Every screen has a link which you can use to submit questions or comments about this tutorial package or the subject material.
  • In order to improve this tutorial package, It is best to ask questions when in doubt.
  • This helps the staff to determine the standard of both the students and the tutorial package.

Tutorial 1 - Play-hookey

  • Some of the best tutorial website on net.
  • Digital or binary logic has fascinated many people over the years.
  • The very idea that a two-valued number system can possibly be the basis for the most powerful and sophisticated computers seems astounding, to say the least.
  • Nevertheless, it is so, and the how and the why of this requires some explanation.

Project 2 - A Simple Psuedo-Random Number Generator

  • The assignment for this project was to produce a psuedo-random number sequence using D-type flipflops.
  • A 555 timer chip was used to produce the clock pulse, which was passed through an inverter before being sent to the 74194 D-flipflop, to reduce noise.
