Title: How can i know the model which the simulator is using?
Post by muffassir on Jan 19^th, 2012, 10:10pm

Hi all,

I am using Cadence 6.1.4 and virtuoso ,gpdk180 and ADE L.

I want to know which model (BSIM3.3, BSIM4.6, BSIM SOI 4.0 or EKV 2.6) of transistor (MOS) is being used by the simulator .how can i do that . Further how can i change the model to EKV 2.6 if possible. what are the steps to be followed.

Thanks in advance..

Muffasir,

Look at the circuit inventory to see which devices are being used. To
change models you need to change the model path to point to the models
you want to use. The tool can use the models, however, you need to
provide them to the tool.

Best Regards,

Sheldon

Do you have parameters for the EKV 2.6 model?

If you have BSIM parameters, likely they include VTH0 because it's a threshold-based model; EKV is not, so it cannot use the same parameters as the BSIM model does. It's actually a fairly difficult problem to extract parameters for a new model.
