Torii-HDL
Torii is a fork of Amaranth HDL that has been modified for use at Shrine Maiden Heavy Industries. It has merged several of the components that were separate into a single package, and also adds new functionality, as well as some internal changes for better integration into tooling.
The evaluation board definitions have also been migrated and are located in the torii-boards repository.
There is also a list of projects using Torii that are using Torii, and we'd love to add yours too!
