News:

Spectrum Software has released Micro-Cap 11, the eleventh generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.

I just received a BSIM V3 model from my MOSFET vendor. I select an NMOS or a PMOS from the Component menu and give it a model name, but then I am unable to change the level parameter to the BSIM level 8 when I click the Edit command button. It only wants to stay with the standard SPICE levels of 1-3. How can I implement the BSIM model into Micro-Cap?

 

The PMOS and NMOS are going to default to a SPICE level 1-3 if the BSIM model is not available when the Attribute dialog box is opened. To make the BSIM model available, copy the model statement into the text area of the circuit file, or enter the file name that the model resides in into the NOM.LIB file. The NOM.LIB file is located in the DATA directory, and the format to enter a new library is to place the following on a new line:

.LIB "library.ext"

where library.ext is the name of the library file. Once either of the two above actions has been performed, an NMOS or PMOS component can be placed in the schematic, or a MOSFET that currently exists on the schematic can be double clicked while in select mode. When the Attribute dialog box opens, a list of all available MOSFET models will be shown in the right hand window. Choose the BSIM model from this list and it will be available for simulation.
