Verification tasks for the Minerva core |
Running the Verification
First make sure you have Nix installed. Then cd
to the root directory of this repo and run:
$ nix-shell
This should run the tests (cache, multiplier, divider) provided by Minerva itself and give you an environment with all the dependencies required for this project. Then, to run the main verification tasks for Minerva provided in this repo:
$ python -m rvfi.cores.minerva.verify
This should run in the order of a few hours.
Progress
- Instruction Checks
- PC forward checks
- PC backward checks
- Register checks
- Causal checks
- Liveness checks
- Uniqueness checks
Scope
The RV32I, RV32M, RV64I and RV64M ISAs are currently implemented but only RV32IM are being tested by integrating with the Minerva core.
