CI: Add OpenTitan build test by mkannwischer · Pull Request #928 · pq-code-package/mldsa-native

mkannwischer · 2026-01-31T03:33:05Z

Add CI workflow to verify that mldsa-native builds correctly
within the OpenTitan (expo) build system. Only builds the test
binary without running the Verilator simulation, as ML-DSA is
too slow for simulation in CI.

Resolves CI: Test OpenTitan integration #886

The Verilator setup seems unnecessary given that we only build, but it allows us to keep the setup action synchronized with mlkem-native, which is worthwhile.

Add CI workflow to verify that mldsa-native builds correctly within the OpenTitan (expo) build system. Only builds the test binary without running the Verilator simulation, as ML-DSA is too slow for simulation in CI. - Resolves #886 Signed-off-by: Matthias J. Kannwischer <matthias@kannwischer.eu>
