Further analysis of the maintenance status of PySpice based on released PyPI versions cadence, the repository activity, and other data points determined that its maintenance is Inactive.

An important project maintenance signal to consider for PySpice is that it hasn't seen any new versions released to PyPI in the past 12 months, and could be considered as a discontinued project, or that which receives low attention from its maintainers.

As a healthy sign for on-going project maintenance, we found that the GitHub repository had at least 1 pull request or issue interacted with by the community.

PySpice : Simulate Electronic Circuit using Python and the Ngspice / Xyce Simulators

Quick Links

Brief Notes

Thanks to Discourse, PySpice now has a Forum hosted at

Disclaimer: PySpice is developed on my free time actually, so I could be busy with other tasks and less reactive.

An issue was found with NgSpice Shared, we must setlocale(LC_NUMERIC, "C"); see

Overview

What is PySpice ?

PySpice is a Python module which interface Python_ to the Ngspice_ and Xyce_ circuit simulators.

Where is the Documentation ?

The documentation is available on the PySpice Home Page_.

Note: This site is hosted on my own infrastructure, if the site seems done, please create an issue to notify me.

Where to get help or talk about PySpice ?

Thanks to Discourse, PySpice now has a Forum hosted at

What are the main features ?

support Ngspice and Xyce circuit simulators
support Linux, Windows and Mac OS X platforms
licensed under GPLv3 therms
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

implement a documentation generator
provides many examples

How to install it ?

Look at the installation section in the documentation.

Pull Request Recommendation

To make it easier to merge your pull request, you should divide your PR into smaller and easier-to-verify units.

Please do not make a pull requests with a lot of modifications which are difficult to check. If I merge pull requests blindly then there is a high risk this software will become a mess quickly for everybody.

News

V1.6.0 (development release)

KiCadTools a proof of concept module to read KiCad 6 .kicad_sch schema file and compute the netlist. This module can be used to perform any kind of processings on a KiCad schema. It is actually hosted in the source but could become a standalone project. For PySpice, it provides a very flexible way to draft a circuit with the help of KiCad and then generate the netlist without using the netlist export feature of KiCad. And thus leverage the writing of fastidious cicruit.

V1.4.3 2020-07-04

A huge effort, thanks to @stuarteberg Stuart Berg, has been made to make Ngspice and PySpice available on Anaconda (conda-forge) for the Window, OSX and Linux platforms. Thanks to the conda-forge continuous integration platform, we can now run unit tests and the examples on theses platforms automatically. Hope this will make the software more robust and easier to run !

PySpice is now available on Anaconda(conda-forge) as well as a wheel on PyPI
Added a post installation tool to download the Ngspice DLL on Windows and to check the installation. It should now simplify considerably the PySpice installation on Windows.
This tool can also download the examples and the Ngspice PDF manual.
On Linux and OSX, a Ngspice package is now available on Anaconda(conda-forge). Note that theses two platforms do not download a binary from Ngspice since a compiler can easily be installed on theses platforms.
Updated installation documentation for Linux, the main distributions now provide a ngspice shared package.
Added a front-end web site so as to keep older releases documentation available on the web.
fixed and rebuilt all examples (but mistakes could happen ...)
examples are now available as Python files and Jupyter notebooks (but some issues must be fixed, e.g. due to the way Jupyter handles Matplotlib plots)
support NgSpice 32 API (no change)
removed @substitution@ in PySpice/__init__.py, beacause it breaks pip install from git
fixed some logging spams
fixed NonLinearVoltageSource
fixed Unicode issue with °C (° is Extended ASCII)
fixed ffi_string_utf8 for UnicodeDecodeError
fixed logging formater for OSX (removed ANSI codes)
reworded "Invalid plot name" exception
removed diacritics in example filenames
cir2py has been converted to an entry point so as to work on all platforms
updated Matplotlib subplots in examples
added a unit example
added a NMOS example (thanks to cyber-g) cf. #221

V1.4.0 2020-05-05

This release is yanked due to broken Windows support.

fixed nasty issue with NgSpice shared for setlocale(LC_NUMERIC, "C"); cf. #172
fixed AC AC_MAG AC_PASAE SIN for new NgSpice syntax
fixed initial_state for VoltageControlledSwitch
fixed LosslessTransmissionLine #169
fixed docstrings for element shortcut methods (thanks to Kyle Dunn) #178
fixed parser for leading whitespace (thanks to Matt Huszagh) #182
fix for PyYAML newer API
support NgSpice 31 API (no change)
added check for CoupledInductor #157

support Ngspice 30 and Xyce 6.10
fixed NgSpice and Xyce support on Windows 10
bug fixes

V1.2.0 2018-06-07

Initial support of the Xyce_ simulator. Xyce is an open source, SPICE-compatible, high-performance analog circuit simulator, capable of solving extremely large circuit problems developed at Sandia National Laboratories. Xyce will make PySpice suitable for industry and research use.
Fixed OSX support
Splitted G device
Implemented partially A XSPICE device
Implemented missing transmission line devices
Implemented high level current sources Notice: Some classes were renamed !
Implemented node kwarg e.g. circuit.Q(1, base=1, collector=2, emitter=3, model='npn')
Implemented raw spice pass through (see User FAQ)
Implemented access to internal parameters (cf. save @device[parameter])
Implemented check for missing ground node
Implemented a way to disable an element and clone netlist
Improved SPICE parser
Improved unit support:
- Implemented unit prefix cast U_μV(U_mV(1)) to easily convert values
- Added U_mV, ... shortcuts
- Added Numpy array support to unit, see UnitValues Notice: this new feature could be buggy !!!
- Rebased WaveForm to UnitValues
Fixed node order so as to not confuse users Now PySpice matches SPICE order for two ports elements !
Fixed device shortcuts in Netlist class
Fixed model kwarg for BJT Notice: it must be passed exclusively as kwarg !
Fixed subcircuit nesting
Outsourced documentation generator to Pyterate_
Updated setup.py for wheel

V0.4.0 2017-07-31

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 2017-02-22

fixed CCCS and CCVS

V0.3.1 2017-02-22

fixed ngspice shared

V0.3.0 2015-12-08

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.
