You'r welcome :-)

Can't be, because it's RTL, which is a technology specific implementation
which can not be protected under a copyright anymore.

That's the whole key issue.
We can't legally build their IP cores with the LibreSilicon process and sell
it within our products and then provide the GDS2 files and ALF layout files on

No reason to be confused.
They could have take the MIT or Apache license (not the GPL because that would
have tainted the issue with the unfree IP cores).
Their IP cores are not Libre. In fact their silicon is unfree AF.
Very simple. Their silicon is *not* Libre.
The fact that they had to introduce a new license which doesn't collide with
their unfree IP proofs it.
