3.1.10 ModelParameters
ModelParameters[Name−>name, par
−>val , † † † ]
defines a local model parameter set
ModelParameters[Name−>name, Scope−>Global, par
−>val , † † † ]
stores a model parameter set in the global subcircuit
database
Command structure of ModelParameters.
In addition to subcircuit and device models, you can also define parameter sets (model cards) that
can be used in conjunction with model references in a circuit description.
The following statement defines a model parameter set for the device type DEFNPN.
ModelParameters[Name −> DEFNPN, IS −> 1.0*^−16, BF −> 100,
BR −> 1, VAF −> 150]
These model parameter sets can be used in model references by means of the Parameters keyword.

3.1.11 GlobalParameters
GlobalParameters[par
−>val , † † † ]
defines global parameter settings
Command structure of GlobalParameters.
With GlobalParameters you can specify settings for global parameters used in a Circuit object, as
for instance TEMP or GMIN.
Global parameter definitions may be self-referencing, i.e. a global parameter may be
specified as a function of one or several others (make sure that there are no circular
references).
The list of global parameters is implicitly appended to the value fields of all model
references in a circuit. Therefore, you can use global parameter settings in a model without
having to pass these settings explicitly in each model reference.
The following examples are valid declarations for global parameters:
GlobalParameters[TEMP −> 300.15, GMIN −> 1.0*^−12]
GlobalParameters[TEMP −> TNOM, TNOM −> 300.15,
GMIN −> 1.0*^−12]
