when I convert cadence layout into Hspice netlist, I found that every MOSfet have no geometric informations in netlist.

for example, following netlist show some geometric informations, ad,as,pd,ps, geo.


********* Hspice netlist

m0 vd vd gnd gnd
+ nmos l=l w=w m='1*d' geo=1
+ ad='w*hdin/2*d' as='w*d*hdout'
+ pd='2*hdin' ps='4*hdout+w*d'

********* end


in my thought, this informations are very important especially layout.

but I cannot extract geometric information from cadence layout.

is there anyone who know that?

thanks.
