# Project Tang

 

## For FPGA Toolchain Users

Project Tang enables a fully open-source flow for Anlogic FPGAs using [Yosys](https://github.com/YosysHQ/yosys)

for Verilog synthesis and [nextpnr](https://github.com/YosysHQ/nextpnr) for place and route.

Project Tang itself provides the device database and tools for bitstream creation.

### Getting Started

### Current Status

 

### Development Boards

## For Developers

This repository contains both tools and scripts which allow you to document the

bit-stream format of Anlogic series FPGAs.

Translation of offical documents can be found [here](https://github.com/kprasadvnsi/Anlogic_Doc_English).

### Quickstart Guide

Take latest TD distribution from [Sipeed.com](https://mega.nz/folder/5AAiSBwB#0jbOgqcrIMJVU9FvCzqb0A/folder/ZY50yRhI)

Point out TD_HOME to your TangDinasty installation and set environment.

```

export TD_HOME=/opt/TD

source environment.sh

```

## Process

To create chip database run:

```

python3 create_database.py

```

In order to get HTML representation of tilegrid data after run:

```

python3 html_all.py

```

### Parts

#### [Tools](tools)

Miscellaneous tools for exploring the database and experimenting with bitstreams.

#### [Util](util)

Python libraries used for fuzzers and other purposes

### Database

Running the all fuzzers in order will produce a database which documents the

bitstream format in the [database](database) directory.

## Credits
