Open Hardware Licensing
summary
CERN OHL v2 is a three‑variant license family: P (permissive), L (weak reciprocal) and S (strong reciprocal); copyleft obligations apply only up to a defined product and do not require publishing sources for defined available components (buyable parts, normal toolchain bits, or items under compatible permissive licenses). FPGA bitstreams count as products, S disallows digital cores as available components, GPL relicensing is not permitted so dual‑licensing is recommended for compatibility.
