When discussing the design and integration of systems on chip and models of systems on chip, the Lego analogy is often brought up. The idea being that with Lego, anyone can put together anything and every component can be combined with all other components. Right. My recent building of Lego set 21327, Typewriter, makes me wonder if the people who talk about Lego-like construction have actually built anything from Legos in the past few decades.
