Project Tang enables a fully open-source flow for Anlogic FPGAs using Yosys for Verilog synthesis and nextpnr for place and route. Project Tang itself provides the device database and tools for bitstream creation.
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.
There are also "minitests" which are small tests of features used to build fuzers.
Fuzzers are the scripts which generate the large number of bitstream.
They are called "fuzzers" because they follow an approach similar to the idea of software testing through fuzzing.
Miscellaneous tools for exploring the database and experimenting with bitstreams.
Python libraries used for fuzzers and other purposes
Running the all fuzzers in order will produce a database which documents the bitstream format in the database directory.
