Simulate electronic circuit using Python and the Ngspice / Xyce simulators
What is PySpicePro ?
PySpicePro is a Python module based on the PySpice module created by Fabrice Salvaire with additions that are not yet integrated into PySpice.
PySpicePro only works with ngspice version 30 (install from ngspice-30_dll_64.zip).
The .meas(ure) keyword has been added through the simulator.measure(..) member function. This allows the use of simulator.options(‘AUTOSTOP’).
Parallelisation is now more convenient with the use of NgSpiceShared.new_instance() where the management of new instances is now completely automated (temporary dll, instances deletions).
pip install PySpicePro
PySpicePro needs to work with a specific version of ngspice. Currently only supporting v30.
What is PySpice ?
Where is the Documentation ?
The documentation is available on the PySpice Home Page.
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
work with Kicad schematic editor
implement a documentation generator
provides many examples
Author of the original PySpice: Fabrice Salvaire
V1.4.0 (development release)
V1.3.2 (production release) 2019-03-11
support Ngspice 30 and Xyce 6.10
fixed NgSpice and Xyce support on Windows 10
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 </faq.html>’_)
Implemented access to internal parameters (cf.
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_Î¼V(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 of
1.2@u_kÎ© / 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.
