Correct, that's a bit of an odd guess. You are definitely working closely with your foundry on something like this, but unless you are building some truly exotic device, I don't think their vendor is getting involved.

Like Melkman says, Broadcom is a good guess. Not only for past rumors, but iirc they also did work with google's TPU (could never figure out if that was actually confirmed?). Interconnect IP like that is definitely in their wheelhouse.
