Don't serialize parameters in certain models for default values. Infer
models from Value field for some kinds of models. Resolve synonyms when
loading models from Spice libraries.
Rewrite the spice exporter to work with the new simulation model
architecture and data model, with many bugfixes related to the latter
two along the way.
Implemented serialization and deserialization of models in symbol fields
through the SIM_VALUE class. We don't carry the Spice legacy of
case-insensitive suffixes, instead we conform to the SI standard (i.e. M
is Mega, not milli, P is peta, p is pico).
Parameter grid value validation is implemented by simply not allowing
any characters that will make the value invalid (instead of highlighting
the field in a red color). This will likely be changed at some point in
the future.
This commit adds parameter display functionality, via a wxPropertyGrid
widget, to the Sim Model Editor. To faciliate that, a SIM_VALUE class is
created to serialize, deserialize, and validate numeric values in the
new parameter grid.
SPICE_MODEL is renamed to SIM_MODEL and split into several subclasses
that correspond to different model kinds.
With that also begin reworking the internal structure of the simulation
model storage. Some models have parameter information extracted from
Ngspice, which was specially patched to faciliate that. The model is
stored and managed by the SPICE_MODEL class (later will be renamed to
SIM_MODEL).
