Programmable Logic Devices

PLDs are specialized integrated circuits (ICs) used to implement digital circuits. These circuits are programmable meaning that they can be preconfigured to create almost any design. Over the years, PLDs have grown in size and complexity and new versions have been created. They give designers a variety of options in developing digital circuits and systems. Today, PLDs have virtually replaced most previously used types of digital logic circuits in modern electronic equipment. This module introduces the concepts of PLDs, describes the various types, and summarizes the basic approach to design, testing, and troubleshooting.
