This repository focuses on designing and simulating logical circuits using Verilog HDL (Hardware Description Language) with the Icarus Verilog simulator. This project aims to provide a collection of Verilog code examples and testbenches for various logical circuits, facilitating learning and experimentation in digital design and HDL programming.

Key Features and Contents:

1. Basic Logic Gates:

   • Verilog code for basic logic gates such as AND, OR, NOT, NAND, NOR, XOR, and XNOR.
   • Testbenches to verify the functionality of each gate through simulation.

2. Combinational Circuits:

   • Implementation of combinational logic circuits including multiplexers, demultiplexers, encoders, decoders, and adders (half and full adders).
   • Simulation files to test and validate the behavior of these circuits.

3. Sequential Circuits:

   • Verilog designs for sequential circuits like flip-flops (SR, D, JK, T) and latches.
   • Testbenches to simulate clock-driven operations and state changes in sequential circuits.

4. Arithmetic Circuits:

   • Code for arithmetic circuits such as ripple carry adders, subtractors, multipliers, and dividers.
   • Test cases to ensure accurate arithmetic operations and handling of carry/borrow bits.

5. Shift Registers and Counters:

   • Implementation of various types of shift registers (serial-in serial-out, serial-in parallel-out, etc.).
   • Design of different counters (binary, BCD, up/down) with corresponding simulation files.

Objective and Impact:

The primary objective of this repository is to enhance understanding of digital circuits and the practical application of HDL in circuit design and simulation. It also provides a strong foundation for more advanced digital design projects and encourages the exploration of complex digital systems using Verilog HDL.
