me years ago, ignorant: "digital processors are vastly superior to analog processors"
me today, working on synchronous logic: "digital logic is just analog logic someone went reeeeal lazy with, like those disposable plastic spoons"
there's really no digital design so simple that you can completely ignore analog effects, it just gets much easier to pretend there aren't any the less involved your design is. "multiclock" is short for "the illusion fell apart, sorry"
also some of the things people normally think of as digital components, like DRAM, EEPROM, or Flash memory, only really have a digital(-ish) interface whereas the guts are completely analog. violate EEPROM write timings, heat it up a little & some 0s will swap with 1s
i remember being really surprised when finding out how a register flipflop is a goldielocks interaction of analog propagation delays. especially that your feedback network can't be too fast or it won't work. only took me 20 years.
