<astrobunny> am i doing it wrong
<astrobunny> i think i sort of understand the thing now, based on your truth tables
<astrobunny> i understand why they call it dfast_mux now, by throwing the output directly out and then feeding the io.q back to ff.d you can quickly get the output and save it at the same time
<astrobunny> ok i may be in dire need of sleep
<whitequark> yes
<whitequark> to both
<whitequark> your diagram looks fairly accurate
<whitequark> i'm impressed that you actually managed it
<whitequark> want to collab on adding it to the docs?
<whitequark> I have sketches I never turned into proper svgs
