3.3 Model Library Management 221
Load two model
definitions from the model
library and store them in
the global subcircuit
database.
List the contents of the
global subcircuit database.
In[2]:= Circuit[
LoadModel["Diode", "Transient", Scope −> Global],
LoadModel["JFET", "AC", Scope −> Global]
] // ExpandSubcircuits;
In[3]:= GlobalSubcircuits[]

JFET, AC SpiceAC Noise SpiceNoise
Removing the model definition automatically clears all alias names for the model. Thus, if you
remove the model "JFET/AC", the aliases "JFET/SpiceAC", "JFET/Noise" etc. will be deleted as
well.
Remove the subcircuit
definition "JFET/AC".
Delete all remaining
subcircuit definitions.

3.3.9 RemoveModelParameters
RemoveModelParameters[name]
RemoveModelParameters[All]
removes the model parameter set name from the global
database
clears the global model parameter database
Command structure of RemoveModelParameters.
RemoveModelParameters allows you to remove individual model parameter sets from the global
parameter database or to clear the database completely. RemoveModelParameters returns the list of
the names of the remaining model parameter sets.
See also: GlobalModelParameters (Section 3.3.5), RemoveSubcircuit (Section 3.3.8).
Examples
Load Analog Insydes.
Define two diode model
parameter sets.
List the contents of the
global parameter database.
