Overview

This repository contains FPGA-based implementations of sequential and combinational logic circuits, along with examples of how to interface them with external devices. It was developed as part of a broader project on Digital IC Functionality Duplication Using Neural Networks, complementing simulation and dataset repositories by providing hardware validation.

---

Quickstart

1. Clone the repository:

git clone https://github.com/Anjanamb/FPGA-Implementation-and-interfacing.git
cd FPGA-Implementation-and-interfacing

2. Open the design files (.bdf, .vhd) in Intel Quartus Prime.

3. Compile the project and upload to a supported FPGA board (e.g., Intel/Altera DE-series).

4. Run the interfacing experiment as described in the relevant folder.

How to run on FPGA

1. Install Intel Quartus Prime.
2. Open a project from Quartus_Projects/.
3. Set correct FPGA board model and pin assignments (see Docs/).
4. Compile the design and program the FPGA.
5. Verify using physical inputs (switches, buttons) and outputs (LEDs, seven-segment, etc.).

Interfacing experiments

This repo includes simple FPGA-to-peripheral interfacing experiments such as:

• Switches → LEDs (basic I/O validation)
• Counters on seven-segment displays
• Shift registers with button inputs
• Clock dividers for timing signals
• (Optional) UART / external communication setups

---

Usage with related projects

This repository complements:

• Sequential-Logic-Datasets-with-Designs – provides simulation datasets.
• Digital-IC-Functionality-Duplication-Using-NN – trains neural networks to duplicate digital IC functionality.

Together, these projects form a complete flow: design → dataset → neural network model → FPGA hardware validation.
