+# Digital Design and Verification Training
+
+## Overview
+This directory contains all lab modules, documentation, and source code for the Digital Design and Verification Training using SystemVerilog. Each lab focuses on a key digital design concept, progressing from basic combinational logic to advanced interface protocols and verification techniques.
+
+## Directory Structure
+- **lab1**: Basic Combinational Circuits (ALU, Priority Encoder)
+- **lab2**: Advanced Combinational Logic (Barrel Shifter, BCD Converter)
+- **lab3**: Sequential Circuit Fundamentals (Programmable Counter)
+- **lab4**: Finite State Machines (Traffic Light Controller, Vending Machine Controller)
+- **lab5**: Counters and Timers (Multi-Mode Timer)
+- **lab6**: Memory Interfaces (SRAM Controller)
+- **lab7**: FIFO Design (Synchronous and Asynchronous FIFO)
+- **lab8**: UART Controller (Transmitter, Receiver)
+- **lab9**: SPI Controller (Master Controller)
+- **lab10**: AXI4-Lite Interface Design (Slave Module)
+
+## Documentation
+Each lab folder contains:
+- **readme.md**: Lab objectives, specifications, block diagrams, state diagrams, timing diagrams, and code framework.
+- **docx/**: Design documentation, diagrams, and synthesis reports.
+- **src/**: SystemVerilog source code for each module.
+- **tests/**: Testbenches and makefiles for simulation and verification.
+
+## Getting Started
+1. Review the lab manual and specifications in each lab's `readme.md`.
+2. Study the block diagrams and state diagrams before coding.
+3. Follow the design steps and code frameworks provided.
+4. Use the testbenches to verify functionality after implementation.
+---
+For details on each lab, see the respective `readme.md` files in each subdirectory.
+
+
+## Testing
+To test a module
+1. Clone the repo.
+2. Go to lab and then task(if present) which you want to run.
+3. Go to test folder and open its makefile.
+4. replace the **PROJECT_ROOT** by the your directory of project .For example ![makefile_project](/Muhammad_Boota/docx/makefile_project.png)
+then save it.
+5. for compile file run in terminal **make c**
+6. For simulation run **make sim**
+7. for terminal view tests run **make**
