hspice - vth value for transistors

[subhashrewa]

hspice

I want to vary the vth value for each transistor in my schematic and see the variation in delay. Can anyone pls help me, how to vary the vth for each transistor in hspice netlist?

i have a perfect solution for this:

as you are using hspice , u must be having demos directory (in hspice installation)

in installation directory u fill find
demo/hspice/variability

this directory has netlists that shows variation in vt and analysis types also..

hope this helps

you can change your model file.
Different model file have different Vth value so change ur model file
