I have designed a model of Graphene Ion-Sensitive FET (Gr-ISFET) biosensor by TCAD Silvaco and I'm trying to import the model to be used in Cadence Virtuoso.
Any idea ?

I do not understand Aparna Sathya Murthy explanation, that seems like a workflow for a mixed mode simulation, which should be feasible using Silvaco for simple circuits.....perhaps I am missing something here !
But, you are probably looking for a SPICE model for your FET. If that's the case, you have to do the compact modeling.
You have select which model is appropriate to capture your device behavior (BSIM is widely used). When you do pick your model, export the necessary IV/CV..etc curves from Silvaco, then follow the extraction procedure using the manual of the model, or some automation tool within the software that prepares your SPICE model (IC-CAP, also known as MPB from Keysight is a commercial tool widely used).
When you do get a good fit, export your model then assign it to a regular FET in Virtuoso. Finally, you can proceed to your circuit implementation.
I hope this helps.
