PVS is a verification system: that is, a specification language integrated with support tools and a theorem prover. It is intended to capture the state-of-the-art in mechanized formal methods and to be sufficiently rugged that it can be used for significant applications. PVS is a research prototype: it evolves and improves as we develop or apply new capabilities, and as the stress of real use exposes new requirements.

For documentation and pre-built binaries, please visithttp://pvs.csl.sri.com/.

In short:0. For Macs, you'll need to install xcode, in Ubuntu, apt-get install build-essential

1. Use your favorite package manager to get SBCL and Emacs
2. git clonehttps://github.com/SRI-CSL/PVS.git
3. cd PVS
4. Run ./configure, use your package manager if, e.g., curl is missing
5. Run make

Notes:

1. This works for Mac M1 natively
2. For some reason the make on Intel Macs pauses a long time at thecompile for list-decls; just be patient.
3. There is a Dockerfile that will create a Docker image for PVS; this canbe used on a Windows platform.
4. If you're using the current version of NASA's pvslib, you will get someerrors. You can temporarily use the pvs8.0 branch ofhttps://github.com/samowre/pvslib.git,which is a fork of it upgraded to work with PVS 8.0 and SBCL.

Let us know atpvs@csl.sri.com if you have problems or suggestions.
