include a model files for nmos and pmos into virtuoso

This is a mos1 (level 1, i.e. Shichman and Hodges) model, and from the documentation:

The consistency between kp, uo, and C_ox(kp = uoC_ox) is checked according to the following rules:

• If tox is not given, C_ox is calculated from the default value of tox.

• If kp is given, uo is calculated from uo = kp/C_ox, whether uo is given or not. If this uo value is different from that specified in the model, a warning message tells you that the specified kp and uo values are inconsistent.

• If you do not give kp and uo is specified, kp is calculated from kp = uo * C_ox.

• If neither kp nor uo is given, their default values are used.

So, given that Cox=εox/Tox and εox=ε0*εr. ε0 = 8.854187817x10−12 [F/m] and εr=3.9, so since tox in the model is 0.1u, Cox=3.4531e-4, and so uo should be 3.0e-5/3.4531e-4. That's 0.08688, but since uo is entered in cm^2/V*s, and this is in m^2/V*s, we need to multiply by 100*100 - so that makes it 868.8 - which is exactly what you see in the model parameters output from spectre (if you've saved them - in ADE you can see this in the results browser). The model has 700 for uo. All it means is that 700 is ignored and 868.8 used instead.

The number of parameters being different may just be a matter of this being a level 1 model - I have no idea what the "ami06" model is. Also, this is a made up model representing an ancient technology - presumably the ami06 model is a characterized model from an AMI process, so has probably had more care put into its creation.

Andrew.
