TINA-TI BSIM3 Support

Silvio,

There are several versions of the BSIM3v3 model. TINA-TI supports the Compact Model Council approved version of BSIM3v3.3. The BSIM3v3.2 version (supported in PSpice as Level 6) is not supported in TINA-TI. I believe that the other model versions (higher than 3v3.3) can also be used in TINA-TI. If you could provide the model, we could check to see if it is supported.

There are several different parameters wit the BSIM3v3 models and some may not be supported, but the model will still run in TINA-TI if the parameters are commented out.

Hi Britt

Thanks for quick reply. I have attached the model I try to include in TINA-TI.

2084.2SK4177.cir

Silvio,

Try this one.

1780.2SK4177.TSM

The Level for BSIM3v3 in TINA-TI is 7. I changed it in the model file and it imported correctly.

Hi Britt

I have imported the macro file but fail to simulate even a simple circuit due to convergence problems. 4784.2SK4177_Test.TSC

Not sure wether import into TINA-TI is the problem or the model itself.

Silvio,

I will take a look at the circuit. I, too, am not sure if the model or TINA-TI is the issue at this point. I'll post back to this thread when I get more information.

Silvio,

The error is caused by the version of the BSIM3v3 model. TINA-TI supports BSIM3v3.1 which does not have CAPMOD 3 as an option. You can change the value of CAPMOD to 2 and the device will function, however, the capacitance equations will be different than the equations that were used when the model was created. You can find the differences between CAPMOD 2 and 3 with a quick google search. If any of the CAPMOD 3 features are key to your use of the model, you may not get the proper results.

I am attaching the .TSC file with the modified model in it.
