Creating custom component models

Along with their standard models, you can use custom .model statements and SPICE subcircuit definitions (.subckt) for placed instances of these components:

  • 3 and 4 terminal MOSFETs (.subckt for 3 terminal versions only)
  • 3 and 4 terminal BJTs (.subckt for 3 terminal versions only)
  • Diode
  • Zener
  • JFETs
  • GaAsFETs (MESFETs)
  • 5 terminal  Opamps   (.subckt definitions only)

This feature is not available for manufacturer-specific components such as the 1N4001G diode. 

Tip. Custom models work on a per component basis. If you want to use the same custom model in multiple components, change one component and then copy and paste it.
