Keelhaul

Generate executable memory-mapped I/O verification test cases from IP-XACT or CMSIS-SVD files.

Dependencies

  • Make sure to run git submodule update --init or equivalent
  • Install Rust from https://rustup.rs/
  • Install just, a command runner for access to convenient build job automation
    • cargo install just

Getting started - try the CLI

The easiest way to use the tool is to run the CLI and explore what it can do:

cd keelhaul-cli

cargo run -- --help

N.b., SoC Hub chip verification so far has used the custom parser available for all subcommands via --use-legacy.

SoC integration guide (register-selftest)

See also. register-selftest.

Further build instructions

  • Make sure everything compiles:
    • SVD_PATH=$PWD/data/test.svd cargo check
  • Build test cases.
    • SVD_PATH=$PWD/data/test.svd just build
  • Build and run (will cause segmentation fault 8-)).
    • SVD_PATH=$PWD/data/test.svd just run

File with test cases can be found at target/<debug | release>/build/register-selftest-<hash>/out/register_selftest.rs.

Limitations

  • While CMSIS-SVD allows specifying otherwise, the keelhaul currently assumes that each individual address uniquely selects exactly 8-bits, as this is the most common case in contemporary architectures. This limitation could be lifted.

Contributing

We are in the process of adapting the library for more use cases across the SoC Hub project. Expect major changes to the project architecture. The libary is an unstable target and it may be difficult to integrate changes at this point.

VS Code settings for rust-analyzer

While we support the `register-selftest", the environment variable based configuration utility, you will need this in your VS Code settings to allow the linter to run without failing.
