Mikolaj Wielgus 748324f4cd Sim: Use O-devices to simulate all tlines (much faster than T-devices) 2022-08-31 15:50:11 +02:00
Mikolaj Wielgus 3b3131ad74 Create class for voltage and current -controlled switches
Unfortunately, along the way it turned out that Ngspice's .probe alli
breaks current-controlled switches. So they won't work in that case for
now.

Mikolaj Wielgus 963900ab83 Sort sim model pins by symbol pin number in sim model dialog 2022-08-26 04:36:48 +02:00
Mikolaj Wielgus a0400791c0 Fix exporting Spice instance lines for multi-part symbols
Only pins from the current symbol part were used: the rest was
incorrectly set to Not Connected.

Also slightly change generation of names for Not Connected nets.

Mikolaj Wielgus 8a6a0ff7dc Allow inferred voltage/current sources to have a single float in Value
Update Opamp test to use this feature.

Mikolaj Wielgus ffab57ffd0 Fix default pin assignment for subcircuit sim models
Instead of using a linear order that incorrectly starts from 0, have all
pins unassigned by default.

Mikolaj Wielgus 6fad25f8ed Allow mapping sim model pins to arbitrary string symbol pin numbers
This change removes the incorrect assumption that symbol pin numbers are
integers and are the same as indexes in the vector storing the symbol
pins.

"~" is now used to denote a floating sim model pin.

Mikolaj Wielgus 0040ffc567 Convert strings to UTF8 before they are input to PEGTL
Otherwise there are QA failures under non-UTF-8 locales.

Mikolaj Wielgus 7cf5138c63 Sim: Bugfixes, mostly for MS Windows compilation errors
Unfortunately, Windows headers define a lot of macros for common words,
so we had to rename some enums to not collide.

We also fix some of the many bugs related to the new simulation
architecture and the Spice Model Editor dialog.

Mikolaj Wielgus 6984f63af8 Sim: Transmission line models
Implement transmission line models and perform some adjustments to
the current models. Add some QA tests.

Mikolaj Wielgus fe38c622a9 Sim: Improvements to model serialization
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.

Mikolaj Wielgus 6450ec6b85 Sim: Spice netlist exporter rewrite
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.

Mikolaj Wielgus ce84a48037 Sim: Implement loading Spice library files
Implement parsing and loading Spice libraries into KiCad. This is done
without any involvement of Ngspice -- we create our own in-tree parser
using PEGTL -- because Ngspice doesn't offer any intermediate output we
could plug ourselves into. We don't parse everything -- just the library
content, so this won't be that much effort.

We implement some basic Spice code preview to give the user a hint what
Spice code eir model will correspond to.

Mikolaj Wielgus 978f01553b Sim Model Editor: Serialize models in fields
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.

Mikolaj Wielgus c5a256291e Sim Model Editor: Display model parameters
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.
