Evaluation boards for Field-Programmable Gate Arrays (FPGAs) and Complex Programmable Logic Devices (CPLDs) are hardware platforms designed to test and develop embedded systems using reconfigurable logic. These boards enable engineers to prototype custom digital circuits without permanent integrated circuit fabrication. As key tools in modern electronics development, they support rapid iteration for applications ranging from aerospace systems to consumer electronics.
