SpiceSharp (Spice#) - electronic circuit simulator
Based on SpiceSharpParser (.NET library that allows to parse SPICE netlists and to simulate them using SpiceSharp library).
This plugin requires .Net Framework 4.7.2 to be installed for it to work.
I managed to run the first test example on my PC. The plugin is not available on the server yet.

I haven't even tried these features myself yet. Support for all types of analysis hasn't been tested. There's still a lot of work to do. Maybe I'll do a direct insertion of values into the circuit description. I wanted to try making a circuit with an amplitude detector. The authors have recently added the ability to specify an amplitude-modulated signal. They have a shell (GUI) in which you can also test circuits.

Hi Viacheslav. As far as I could see, the plugin you created works very well, it just has some very minor details, like not recognizing either "u" or "μ" for micro. By the way, handling that is a configurable option in ltspice. So you shouldn't be the first one to have problems with that.
As for the analyses that spice# has, it's just a matter of discovering them, since the documentation they have is very little, and for example, I don't know what convention they followed to enumerate the nodes of the controlled sources. I took the one they use in the Qucs simulator, but there is no standard for that.
I saw the GUI for windows that you mention on github, except that they didn't compile it... or at least I didn't find it, only the source code.
Best regards.
Alvaro.

Similar project. I assembled it, but I haven't tried it in work.

Plugin updated.
Changes:
- Plugin adopted to a new SMath Studio Core infrastructure;
- Folders removed from the output artefacts.

Hi Viacheslav. Great work, congratulations. Some questions:
I was able to introduce an ampop, which is a fairly theoretical model without many physical parameters. How did you introduce the diode model?
Is it possible to import ltspice models more or less automatically?
Another question: how could V1, V2, and V3 be graphed in your 3DPlot plugin? The CreateSpace function is new, isn't it? Do you have examples of how to use it? Generally, these graphs can't be created in simulators, and the data must be exported to MATLAB or other similar software.
Best regards.
Alvaro.

I can tell you how to proceed, i.e. the algorithm for setting the problem.
If you want to simulate the scheme, then you need an example. Nowadays, in the programming world, it is common to accompany source texts with tests. These tests, as a rule, cover many typical tasks.
You need to find these texts, see the link below. Then introduce Gemini to the matter so that he can help create an adequate syntax. I simply throw the test sources into the chat as an example and say what I need.
Is it possible to import ltspice models more or less automatically?
Show me an example, if I do this, then yes, it can be done almost automatically and I will tell you how.

Not at the moment, but I can make it so that it will be possible. I don't have enough time to finish this plugin, as it is a bit more complicated than X-Y Plot.
Yes, CreateSpace() is a new function, I asked Gemini to make it, but I haven't used it yet. The plugin does not support the data format returned by this function.

Hi Viacheslav. Thanks, the link you provide shows how to simulate components, for example, a diode:
One more question: An option to have outputs with units? I think it would just be a matter of identifying time, volts, and amperes. It would be very practical to be able to use milli, micro, and nano prefixes.
Best regards.

Good advice. We need to think bigger. I want to add elements from the sheet to the schema code. For now, this is done in a limited way, because there is not enough time to think of a convenient solution, but in general it will be possible to both set variables with units separately and get a response with units.
There is probably some support for this in the library code. I'll take a look.
