3.4 Expanding Subcircuits and Device Models
Before Analog Insydes can set up a system of circuit equations from a netlist, all subcircuits and model
references in the netlist must be expanded and instantiated with ExpandSubcircuits. Subcircuit
expansion is taken care of automatically by CircuitEquations, so that, except for debugging
purposes, there is usually no need to call ExpandSubcircuits explicitly.
3.4.1 ExpandSubcircuits
ExpandSubcircuits[netlist, opts]
Command structure of ExpandSubcircuits.
expands and instantiates all subcircuit and model
references in netlist
Given a Netlist or Circuit object, ExpandSubcircuits expands all model references and stores
model definitions to the global model data base. It returns a Netlist object. Expanding subcircuits
is taken care of automatically by CircuitEquations, so that there is usually no need to call
ExpandSubcircuits explicitly nor to take care of its options.
ExpandSubcircuits has the following options:
option name
default value
AutoloadModels True whether to load device models
automatically from the model library
DefaultSelector None the default value to be used to replace
generic subcircuit selectors
HoldModels None a list of patterns matching the names and
selectors of model references that shall
remain unexpanded
InstanceNameSeparator
Inherited[AnalogInsydes]
the separator string for name components
of model variables and reference
designators (see Section 3.14.2)
KeepLocalModels False whether to keep local model definitions in a
netlist after subcircuit expansion
