To ensure compatibility and seamless integration with existing hardware and software ecosystems distributed under copyleft licenses, this project adopts compatible open-source and open-hardware licensing models for its individual component categories.
All gateware components, including RDL specifications, RTL sources, HDL modules, hardware integration files, and related build scripts, are licensed under the CERN-OHL-S-2.0 license.
The CERN Open Hardware Licence Strongly Reciprocal variant ensures that any modifications, derived works, or redistributed hardware designs remain open under the same license terms. This is intended to preserve transparency, reproducibility, and long-term openness of the hardware ecosystem built around the project.
All software components, including programs written in C and Python, firmware utilities, host-side tools, testing infrastructure, and related build scripts, are licensed under the AGPL-3.0-or-later license.
The GNU Affero General Public License ensures that improvements and modifications remain available to the community, including in network-accessible deployments and cloud-based environments.
All documentation, including technical documentation, diagrams, illustrations, specifications, tutorials, and related build scripts, is licensed under the CC-BY-SA-4.0 license.
This license allows redistribution and adaptation of the documentation, provided that attribution is preserved and derivative works are shared under the same terms.
This project may include or redistribute third-party libraries, tools, or external components. Such components remain licensed under their respective original licenses and copyright terms.
Users and contributors are responsible for complying with the license requirements of all included third-party dependencies.
