Spice#/SpiceSharpParser

SpiceSharpParser is a .NET library that allows to parse SPICE netlists and to simulate them using SpiceSharp.

Installation

SpiceSharpParser is available as NuGet Package.

Quickstart

Parsing a netlist and executing a simulation is relatively straightforward. For example:

using System;
using System.Linq;
using SpiceSharpParser;

namespace SpiceSharpParserExample
{
    class Program
    {
        static void Main(string[] programArgs)
        {
            var netlistText = string.Join(Environment.NewLine,
                "Diode circuit",
                "D1 OUT 0 1N914",
                "V1 OUT 0 0",
                ".model 1N914 D(Is=2.52e-9 Rs=0.568 N=1.752 Cjo=4e-12 M=0.4 tt=20e-9)",
                ".DC V1 -1 1 10e-3",
                ".SAVE i(V1)",
                ".END");

            // Parsing part
            var parser = new SpiceNetlistParser();
            var parseResult = parser.ParseNetlist(netlistText);
            var netlist = parseResult.FinalModel;

            // Translating netlist model to SpiceSharp
            var reader = new SpiceSharpReader();
            var spiceSharpModel = reader.Read(netlist);

            // Simulation using SpiceSharp
            var simulation = spiceSharpModel.Simulations.Single();
            var export = spiceSharpModel.Exports.Find(e => e.Name == "i(V1)");
            simulation.EventExportData += (sender, args) => Console.WriteLine(export.Extract());
            var codes = simulation.Run(spiceSharpModel.Circuit, -1);
            codes = simulation.InvokeEvents(codes);
            codes.ToArray(); //eval
        }
    }
}    

Compatibility

PSpice

SpiceSharpParser is able to parse some of PSpice netlists. At the moment due to lack of implementation of LAPLACE and FREQ (part of analog behavioral modeling) and other features parsing or simulation can fail.

Capabilities

Analog Behavioral Modeling supported:

• POLY(n)
• TABLE
• VALUE
