Dear Nudrat Sufiyan

try this code

method newton itlim=25 trap maxtrap=20 carriers=2

output con.band val.band

solve init

save outf=init00.str

solve vstep=0.1 vfinal=0.6 name=gate

log outf=V_bd_vg10_1e16.log

solve vdrain=0 vstep=0.1 vfinal=10 name=drain compl=2 cname=drain

log off

save outf=impact.str

tonyplot impact.str -set hole_conc.set

tonyplot V_bd_vg10_1e16.log -set V_bd.set

extract init infile="V_bd_vg10_1e16.log"

extract name="Vbd1" x.val from curve(v."drain",i."drain") where y.val=2
