I see 16 nfets in the resulting .spice, which makes sense for my layout.
Using this script on the same layout:
extract do local
extract all
ext2sim labels on
ext2sim
extresist tolerance 10
extresist
ext2spice lvs
ext2spice cthresh 0.01
ext2spice extresist on
set filename [cellname list window]
set spicefilename [lindex [split $filename .] 0]
ext2spice -d -F -o "../pex/$spicefilename.spice"
I see 6 nfets. Little weird that the number is different. Should I expect this?
The real troubling part is that in the latter extraction, an nfet which serves as a power on reset is not in the netlist. at least I can't find it. Anyone heard of this kind of issue before?Tim Edwards

(the name of the power on reset signal) to its corresponding nfet.
Also, the number of nfets in this file is 13John Kustin
