Pretty good but they don't have any analog bits. Of course analog
depends on process more that digital so analog is pretty much company
oriented (or group oriented where I am as our group has analog blocks
nobody else has). Still, it looks like the open cores cover a lot of
ground and can reduce some cost particularly with ARM which has a
royalty involved no matter who builds under license.
