Spice# is a Spice circuit simulator written in C#. The framework is made to resemble the original Berkeley Spice version, but some parts have been altered/improved to fit into the .NET framework.
Unit tests to compare Spice# to Spice 3f5 are used to verify the models. Nevertheless, some small numerical errors may be present as a direct consequence of bug fixes and structural differences.
Please note that this project is by no means meant to compete with existing commercial Spice simulators. The project started out as a means to learn and understand electronic circuit simulators.
Spice# is available as a NuGet Package.
You can find documentation here. It includes a small tutorial and the API documentation.
