@Tim Edwards Do you know what are the

special_nfet

transistors? My guess is that these are fixed geometry (no W or L can be changed w.r.t. the default) devices uses in special contexts (memory decoders, stdcells and such). I see these flavors: •

special_nfet_01v8

•

special_nfet_latch

•

special_nfet_pass

•

special_nfet_pass_flash

•

special_nfet_pass_lvt

@Ethan Sifferman you can use a regular

nfet_01v8

transistor, set the correct and allowed W / L size and change the model name.

@Stefan Schippers I believe they are devices for which there are no binned models. I’m not sure how simulation handles them.

@Mitch Bailey My understanding is that these devices should not be used in "user" designs. Some of these are used in standard cells, but tested and characterized only there, not allowed in other contexts. And yes, there are no 'bins', only one fixed W/L size.
