Simulate electronic circuit using Python and the Ngspice / Xyce simulators

PySpice : Simulate Electronic Circuit using Python and the Ngspice Simulator

• Quick Link to Production Branch
• Quick Link to Devel Branch

Overview

What is PySpice ?

PySpice is a Python module which interface Python and the Ngspice circuit simulator.

What are the main features ?

• licensed under GPLv3 therms
• support Linux, Windows and Mac OS X platforms
• implement an Ngspice shared library binding using CFFI which support external sources
• implement (partial) SPICE netlist parser
• implement an Oriented Object API to define circuit
• export simulation output to Numpy arrays
• plot using Matplotlib
• handle units
• work with Kicad schematic editor
• implement a documentation generator
• provides many examples

Where is the Documentation ?

The documentation is available on the PySpice Home Page.

How to install it ?

Look at the installation section in the documentation.

News

V1.1.0

• Enhanced shared mode
• Shared mode is now set as default on Linux

V1.0.0

• Bump version to v1.0.0 since it just works!
• Support Windows platform using Ngspice shared mode
• Fixed shared mode
• Fixed and completed Spice parser : tested on example's libraries

V0.4.2

• Fixed Spice parser for lower case device prefix.

V0.4.0

• Git repository cleanup: filtered generated doc and useless files so as to shrink the repository size.
• Improved documentation generator: Implemented format for RST content and Tikz figure.
• Improved unit support: It implements now the International System of Units. And we can now use unit helper like u_mV or compute the value of 1.2@u_kΩ / 2@u_mA. The relevant documentation is on this page.
• Added the Simulation instance to the Analysis class.
• Refactored simulation parameters as classes.

V0.3.2

• fixed CCCS and CCVS

V0.3.1

• fixed ngspice shared

V0.3.0

• Added an example to show how to use the NgSpice Shared Simulation Mode.
• Completed the Spice netlist parser and added examples, we could now use a schematic editor to define the circuit. The program cir2py translates a circuit file to Python.
