Cores catalog

FPGA/ASIC/HDL/IP cores

An evidence-first catalog for fast engineering triage: reusable value, license risk, verification depth, and board fit before you open the upstream repo.

How to read cardsA card does not replace upstream docs or license review. Check warnings and commercial-use clarity first, then tests, board evidence, and toolchain fit.Why no featured vendor laneRanking is driven by evidence, review status, and reusable signals. Namespace or vendor identity does not create a privileged lane.
