myspice

A collection of utilities to work with SPICE simulations

Installation

pip install myspice

About

myspice was created as a tool to help with the building of ngspice tutorials.

Since others may find it useful, I have released it with a permissive license. My plan is to keep adding functionality as it matures.

The main utility in myspice is ngextract, a script that takes ngspice output and extracts the data generated using .print statements so that it can be easily read and processed by other software. I wanted to have a simple command line tool.

When used as part of the myspice package, the ngextract module returns a dictionary of numpy arrays, which makes integration with matplotlib straightforward.

What myspice is not

There are other good Python packages that provide a more comprehensive integration with solvers such as ngspice or Xyce:

• PySpice — Simulates circuits with ngspice or Xyce and builds netlists directly from Python.
• PyLTSpice — Automates running and parsing results from LTspice.
• spicelib — Successor to PyLTSpice, with broader support for LTspice, ngspice, and Xyce.
