@User I also noticed that the sizes off the extracted devices don't appear to match what I expect. Each finger should be

6u

wide and

1u

long but the extraction produces a

w=1200

and an

l=200

with a

.option scale=5000u

, so the ratio makes sense but I can't arrive at

6u/1u

with the numbers I see. Is

.option

local to the subcircuit it's declared in?
