Key Features:

• VHDL Coding for Digital Circuits: All projects are developed using VHDL to describe the functionality and behavior of various digital components such as gates, multiplexers, adders, and counters. • Simulation with Quartus II and ModelSim: The projects make use of Quartus II for circuit design and ModelSim for functional simulation, allowing for testing and verification of digital systems. • FPGA Implementation: Many of the circuits are implemented on FPGA boards, providing real-world testing and validation for designs.

Projects Include:

1. Basic Logic Gates - Implementation of basic logic gates such as AND, OR, NOT, NAND, NOR, XOR, and XNOR.
2. Combinational Circuits - Design of multiplexers, demultiplexers, encoders, and decoders.
3. Flip-Flops and Registers - Design and implementation of SR, JK, D, and T flip-flops, as well as registers for data storage.
4. Counters - Both synchronous and asynchronous counters, including up, down, and up/down counters.
5. Arithmetic Circuits - Full adders, half adders, binary and BCD adders, and subtractors for arithmetic operations.
6. State Machines - Finite State Machines (FSM) design, including simple examples for sequential logic control.

Tools and Software: • Quartus II: For designing and synthesizing digital circuits. • ModelSim: For simulating the VHDL code and verifying the functionality of the designs. • FPGA Hardware: The final designs are downloaded onto FPGA boards for hardware implementation and verification.
