How to add new SPICE transistor model?

Heru,

It depends on the type of model you are trying to add. If the model is a .SUBCKT, then you can use the New Macro Wizard tool to simply add it and associate a symbol to it. If you are trying to add a .MODEL transistor model, you will need to turn it into a .SUBCKT file by simply placing it in a netlist as a .SUBCKT call.

.SUBCKT NEWTRAN G D S

M1 G D S MOSFET

.MODEL MOSFET ......

.ENDS NEWTRAN

In the example above, you would create the file NEWTRAN.lib with a text editor and cut and past the .MODEL for MOSFET into the file. Add the statements and then use the New Macro Wizard to import the .SUBCKT.

This will add the transistor as a .TSM file to your computer that you can import at any time using the File--> Import -->Macro...
