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 https://sourceforge.net/p/ngspice/bugs/490/
PySpice is a Python module which interface Python to the Ngspice and Xyce circuit simulators.
The documentation is available on the PySpice Home Page.

Look at the installation section in the documentation.
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.
Authors: Fabrice Salvaire and contributors
- support Ngspice 30 and Xyce 6.10
- fixed NgSpice and Xyce support on Windows 10
- bug fixes
- 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
- Enhanced shared mode
- Shared mode is now set as default on Linux
- 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
- Fixed Spice parser for lower case device prefix.
- Git repository cleanup: filtered generated doc and useless files so as to shrink the repository size.
- Improved documentation generator: Implemented
formatfor 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_mVor compute the value of1.2@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.
- fixed CCCS and CCVS
- fixed ngspice shared
- 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.
