nf

and

mult

are both instance parameters.

nf

(# of fingers) is used when choosing the right model based on geometrical dimensions (total w, l).

mult

is the multiplicity factor. when

mult=2

is set on a mos instance it will be netlisted with '`m=2 mult=2`'.

m

is the multiplication factor, it simulates parallel devices. ' `mult`' is the same thing, it is replicated because '`m`' is not an available parameter to be evaluated by formulas (for example for montecarlo variation calculations). nf is not displayed in the symbol to avoid displaying too much information on the schematic.
