NgSpice

This repository provides a Julia wrapper for NgSpice library.

In a Julia REPL,

] add https://github.com/JuliaComputing/NgSpice.jl
using NgSpice

To start an an interactive mode,

using Plots
NgSpice.interactive()

• Hit ~ for initializing the NgSpice

Run the Ngspice simulations commands!
For example:

source /filepath/netlist # without quotes
display                  # prints all vectors and constants
plot vector1 vector2     # plots the real part of vector by default

Note: It is not necessary for .cir to be placed in bin folder as long as full path is specified.

Additional to usual plot parameters, different modes of retrieval can be set with:
plot -x space seperated vectorlist
where x takes following modes:

For a non-interactive and more Julia-like experience checkout this tutorial.

Additionally, to simulate a complex_circuit.sp file with multiple plotting statements, run

using NgSpice
using Plots
source_sp("path/to/the/complex_circuit.sp")
