A curated directory of open FPGA IP cores, with a quality signal you can trust: many listings carry earned badges from our open toolchain, lints clean, testbench passes, synthesizes, formally proven. Filter by what you actually need.
84 curated open cores across 20 categories. Badges are earned only where LibFPGA has actually run the checks; the rest are marked verification pending. Own a listed repo? Claim it by manifest file or GitHub sign-in.
Want our own building blocks? The libfpga library is a first-party, formally-verified collection listed right here in the registry. Prefer to learn a pattern hands-on first? Try the runnable recipes.
