From the link the only versions I could see are Vivado tool versions which appear to be year based. If the IP is bundled with the tool, then use the tool version (oldest version you tested with) if there is no other versioning. A 1.0 version really just sounds like you made it up. Something like bindings/sifive/sifive,blocks-ip-versioning.yaml is what I'm looking for. Rob
