## Introduction

The award-winning OpenFPGA framework is the **first open-source FPGA IP generator** supporting highly-customizable homogeneous FPGA architectures. OpenFPGA provides complete EDA support for customized FPGAs, including Verilog-to-bitstream generation and self-testing verification. OpenFPGA opens the door to democratizing FPGA technology and EDA techniques with agile prototyping approaches and constantly evolving EDA tools for chip designers and researchers.

**If this is your first time working with OpenFPGA, we strongly **recommend you watch the** [introduction video about OpenFPGA](https://youtu.be/ocODUGcYGqo)**

A quick overview of OpenFPGA tools can be found [**here**](https://openfpga.readthedocs.io/en/master/tutorials/getting_started/tools/).
We also recommend potential users check out the summary of [**technical capabilities**](https://openfpga.readthedocs.io/en/master/overview/tech_highlights/#) before compiling.

## Compilation

**A tutorial **video about **how to compile** can be** found [here](https://youtu.be/F9sMRmDewM0)**

Before starting, we strongly recommend you read the required dependencies at [**compilation guidelines**](https://openfpga.readthedocs.io/en/master/tutorials/getting_started/compile/).
It also includes detailed information about the docker image.

**Compilation Steps:**

```bash
# Clone the repository and go inside it
git clone https://github.com/LNIS-Projects/OpenFPGA.git && cd OpenFPGA
make all
```

---

**Quick Compilation Verification**

To quickly verify the tool is well compiled, the user can run the following command from the OpenFPGA root directory.
```bash
source openfpga.sh
run-task compilation_verification --debug --show_thread_logs
```

*Python3 and iVerilog v10.1+ are required. GUI will pop up if enabled during compilation.*

---

**Supported Operating Systems**

We currently target OpenFPGA for:
 1. Ubuntu 18.04
 2. Red Hat 7.5

*The tool was tested with these operating systems. It might work with earlier versions and other distributions.*

## Running with pre-built docker image

```bash
# To get the docker image from the repository, 
docker pull ghcr.io/lnis-uofu/openfpga-master:latest

# To invoke openfpga_shell
docker run -it ghcr.io/lnis-uofu/openfpga-master:latest openfpga/openfpga bash
```
