how to find leakage current in nmos transistor

[sumandeepkaur.15]

i want to fimd leakage current in nmos and my hspice coding is...
vdd 1 0 dc 1v
m 1 2 0 0 nmos w=1u l=65n
vgs 2 0 dc -.1v
.include '/home/student1/65nm_bulk.txt'
.tran 5n 200n
.probe tran i1(m) i2(m)
.option post probe
.end

but result is show zero value.is my code correct..if not then tell me how we calculate leakage in nmos...
plz reply

Set vgs=0V and probe i1(m) for drain leakage.
Set Vgs=1V and Vds=0, and probe i2(m) for gate leakage.
