Abstract
The article explores the application of digital circuits, such as logic gates, logic functions, flip-flop, and automata, using the Nexys 4 DDR platform from Xilinx and the Vivado software. The Nexys 4 DDR, featuring the Artix-7 FPGA, provides a robust environment for designing and testing digital systems. It allows for efficient implementation of various digital functions through hardware programming and simulation. The use of Vivado software eases the creation, simulation, and deployment of custom digital circuits, highlighting the versatility and power of FPGA technology in real-world applications. This paper highlights key principles, practical implementations, and design considerations involved in using these tools for digital circuit applications.
