You can use HoldModels to prevent expansion of a particular device type or model instance.
Do not expand references
to "Q2N2222" devices.
In[10]:= ExpandSubcircuits[buffer,
DefaultSelector −> AC, Protocol −> Notebook,
HoldModels −> Model[_, "Q2N2222", _]]
Searching model libraries for model "BJT/AC".
Loading model "BJT/AC" from library FullModels‘.
Instantiating model "BJT/AC" for reference Q$T3.
Instantiating model "BJT/AC" for reference Q$T4.
Instantiating model "BJT/AC" for reference Q$T5.
Out[10]= NetlistChecked, 37
If you want to flatten a netlist completely after partial expansion, you must specify
KeepLocalModels −> True to prevent local model definitions and parameter sets from being discarded
by ExpandSubcircuits.
Keep the transistor
instance "Q$T3" and
references to "Q2N2222"
devices; do not discard
local model card data for
these devices.
