VBIC_Model:VBIC Model
The Spectre vbic (Vertical Bipolar Inter-Company) model is translated to the ADS VBIC_Model. For translation information on the BJT device, refer to BJT Device.
For more information on the ADS model, place the model in a schematic and choose Edit > Component > Edit Component Parameters to view the model parameters. You can also click Help in the component editor dialog box for additional information.
Example Spectre Command Line:
- model vbic_mod vbic type=npn
Spectre Netlist Syntax:
- model mname vbic type=[npn|pnp] [param=value]*
ADS Netlist Syntax:
- model mname VBIC NPN=[0|1] PNP=[0|1] [param=value]*
ADS Schematic Symbol:
Model Parameters:
For information on parameter format, refer to Using Parameter Mapping Tables to Understand a Translation.
