We are planning on adding our Vita Programming Language Frontend, Intermediate Representation Optimizations, a Vita Intermediate Representation if deemed necessary, and a backend for the Vita FPGA Architecture to our fork of LLVM's circt project. Mainlining our patches is welcome.
We are also evaluating any useful fully open source hardware description language compilers that exist, but are missing one or more fully open source FPGA backends so that we can add our Vita FPGA Architecture backend.
The word "Vita" is a generic latin word meaning "life". My name is Vitalii Skikun, so I can't be sued for using part of my name to name stuff. (See how a man named Sattar Buksh in Pakistan won a lawsuit initiated by Starbucks Corporation: https://food.ndtv.com/news/starbucks-versus-sattar-buksh-story-of-the-fascinating-dispute-that-went-on-for-years-9257901)
"VitaOS" is a revoked USPTO trademark and Sony Corporation was refused the trademark of the word "Vita" in the European Union and no one owns the trademark for the word "Vita" in the United States because they can't.
So you companies better not sue me over the word "Vita", cause if you do, I'll win in court.
Edit: I forgot to mention that I'm not gonna use Yosys and NextPNR because they are reverse engineering efforts, and that is a unwelcome gray area legal territory for us to be in.
