Here is one: https://en.wikichip.org/wiki/cavium/microarchitectures/vulcan https://en.wikichip.org/wiki/cavium/microarchitectures/vulca... I don't know the details of how much rework they had to do.

Ironically Cavium may have gone through the same process with their previous design, but given that they then acquired this one from broadcom, perhaps it didn't go very well! I have no concrete information though.
