Open-Source Ada: From Gateware to Application

This is specifically for hardware. Looks really cool!

I’ve always been confused about Ada the language and its licensing though. I know this project is open source but is the language as well? It’s unclear to me, though I may be missing information

What do you mean with "is the language open source"? The Ada specification is public [0] but not open source -- but the C and C++ specifications are not open source either, in the normal sense of the term. And like with C and C++, there are both open source and proprietary compilers for Ada, see e.g. [1]

What's mostly not open source (FAFAIK) is SPARK, the formal verification framework for Ada.

SPARK tools are also open source. The main tool `gnatprove` is based on GCC as well. https://github.com/AdaCore/spark2014

It's not a community project, AFAICT. Few people know how to build it from source.

That links gives me a 404. Does it require membership of some organization before you're allowed to view it?

edit: did you mean https://github.com/AdaCore/spark2014 ?
