Totally from-scratch IP blocks exist but is uncommon.

When there are no helpfull primecell IDs giving the secret
of ancestry away readily, fall back to comparing register maps,
this usually reveals the family of hardware and possible
ancestors. (Like was quickly done for the 8250 derivate
serial.)
