Aren't devices merchant, own ASIC/NPU is an exception.

Magic FPGA gen1+gen2
Most catalysts (Are all?)

Merchant stuff is:

Why would different logo on chip imply better applicability for your

Regardless of the logo, you need to do your due diligence and know

That seems very flexible definition. How do we define merchant and
custom, how much IP can you buy, before it becomes merchant? Is EZchip
NP3c custom or merchant? Is Alcatel FP3 custom or merchant?
Would we know if Juniper had bought 20% 60% 90% of IP for Trio from
someone? I don't believe they did, but would we know? Would it matter?
