BSIM3/4 to EKV model translator ?

Anyone is aware if such tool exists ? If yes, do you have a link ?

Thnx,

I don't think it is wise to use a model translator. You will sufer from inaccurancy. The parameter used in BSIM aren't based on real physical ones.

bsim to ekv

You may use ICCAP. Generate curbes using BSIM model and then make ICCAP to fit them using the EKV model.

bsim2ekv problems

I know that using a model-to-model translator will reduce accuracy, but what other options do I have ?

Thnx,

generate ekv model parameters

There a BSIM2EKV translator availlable on request from EPFL. It os an OK starting point, mostly to generate a template for the model, and copy all the paraistics etc... Definitely needs some fine-tuning to get a decent model. One of the problem is that it does 'blind' curve fitting, and takes the parameters (PHI, GAMMA...) too far from their reasonable physical values, and then the model deteriorates as the conversion progresses. Ic can be helpful, but some furhter fitting will be needed.
