sebench 0.4.0

Hierarchical, multi-fidelity system simulation framework with a hardware-in-the-loop seam.

sebench

A Python framework for hierarchical, multi-fidelity system simulation with a hardware-in-the-loop seam.

Build abstract models of complex systems, drill down into concrete implementations, swap in real hardware without touching the rest, and get deterministic replay, trace analysis, and requirement verification along the way.

Install

pip install sebench

The 3D-printer demo (printerlab) lives in this repo as a reference implementation. It is not published to PyPI.

Quickstart

git clone https://github.com/<you>/sebench.git
cd sebench
make setup              # uv sync + pre-commit install
make demo-pyramid       # simulate printing a 20 mm pyramid (~10 s wall-clock)
make report-server      # open http://localhost:8765 to view the report

Development workflow

Daily work

git add <files>
git commit -m "your message"   # pre-commit runs: ruff fix, format, whitespace
git push                       # pre-push hook runs: lint + typecheck + unit tests

If pre-commit fixes files, re-add them and commit again:

git add <files>
git commit -m "your message"

What CI does automatically (no action needed)

On every push to main or pull request:

• Ruff lint + format check
• Mypy type check
• Determinism lint
• Full test matrix (Python 3.11 / 3.12 / 3.13 on Ubuntu, macOS, Windows)
• Coverage report (must be ≥ 80%)
• Uploads coverage.xml and test-results.xml as artifacts

Releasing to PyPI

1. Go to Actions → Release sebench to PyPI → Run workflow
2. Enter the version number (e.g. 0.2.0)
3. Click Run workflow — everything else is automatic

The workflow will: bump pyproject.toml, commit + tag on main, run the full test suite, build the wheel, publish to PyPI, and create a GitHub Release with the build artifacts.

Prerequisite: configure PyPI Trusted Publishing for this repo at pypi.org (Settings → Publishing).
