Programmable Logic Devices (PLDs) are electronic components used to build digital circuits. They can be programmed to perform specific logic functions, allowing designers to create custom hardware solutions. PLDs are versatile and can be reconfigured, making them ideal for prototyping and applications where flexibility is essential. Common types of PLDs include Field-Programmable Gate Arrays (FPGAs) and Complex Programmable Logic Devices (CPLDs). These devices consist of an array of programmable logic blocks and interconnections, enabling users to implement complex logic designs. PLDs are widely used in various industries, including telecommunications, automotive, and consumer electronics.
