Adds a Nix environment which provides a development shell for the formal verification flow. All dependencies are fetched and built upon entering the shell (nix develop .#formal), except for the proprietary Cadence Jasper. The dev shell (nix develop .#formal-dev) is identical to the normal shell, but prints some information on how to swap out components. This is also documented in the README. Documentation on how to use this environment is added to the dv/formal/README.md The provided Makefile/.tcl scripts make assumptions about the environment they are run within which are provided by the Nix environment. Using Nix is the recommended way to run this flow, but if you cannot do this, you will need to duplicate the setup done by Nix in terms of environment variables and provided dependencies. Jasper Gold options: - allow_unsupported_OS is required on both the machines I use. - acquire_proj means that if JG is killed (which happens somewhat often) the next it runs it will still be able to take ownership of the project.
