WARNING!

Recently Lattice scrapped free licenses of ispLEVER as commented on:
- https://hackaday.com/2020/06/05/lattice-semiconductor-targets-bitstream-reverse-engineering-in-latest-propel-sdk-license/#comment-6251870
You can also look at official Lattice page for confirmation:
- http://www.latticesemi.com/licensing
Therefore please verify that you have valid ispLEVER license before buying anything from Lattice!
