Nice writeup! Do you know around what time repeaters were started to be used for clock trees? I also wonder about the two phases. Is that still commonly used?

- kens 3y agoOne lecture from 2004 discusses the buffered clock tree in the Alpha 21064 (1992), while the 386 (1985) didn't use them, so that gives a time period. As far as two phases, the lecture says that edge-triggered (rather than two-phase) is most popular (page 16). But I don't know about modern design.
