> Wait, they needed testing late last year to figure out the chip was physically too big to be used in an iPhone? The area that a chip takes up is the physical size of the part, any passives it needs, and the space to route the traces to connect them all and meet noise/emf specs. It can take a very long time to figure out if a part is "too big" because it requires iterative design/redesign time by engineers, and it's not knowable before they begin working with the part.
