Is there any method which set the resistor in Spice model ?

Thanks for reading.

I'd like to define the resistor between source and drain in spice model.
But I didn't find such a parameter in BSIM3 spice model paramter.
That I want to do is to make the leakage source which depends on VDS.
I don't want to change the other factors (Vth, Isat, etc).
Is there any method in hspice model ?

There isn't such a thing in the official standard BSIM3.

Some vendors may have added a proprietary extension to the model, though I'm not aware of any.

If at first you do succeed, STOP, raise your standards, and stop wasting your time.

why don't you add in schematic level??

It could be a nuisance to do in schematic, if you have many instances.

Can't you just create a subcircuit with the resistor and device model?
