help! How can I plot the Vth in analog design env

[L.S.D]

iv plot nmos vth

In cadence analog design env,how can I polt the threshold voltage of an nmos as a function of channel length L with spectre?
how can plot the device's parameter?

 

[DenisMark]

plotting threshold voltage in spectre

It's similar to:

 

[lvlei0309]

plot threshold voltage with cadence

Vth can directly be seen

Do it as usual like any other plots. However you have to do the plot function of length point by point. Each time you change the length measeure le Vth and repeat that step untill the curve is done.

use calculator of ADE to get vth

can I get the polt like this directly?

plot by hand?
