2.1. V1.3.0 (development release)

2.2. V1.2.0 (production release) 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

2.3. V1.1.0 2017-09-06

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

2.4. V1.0.0 2017-09-06

  • 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

2.5. V0.4.2

  • Fixed Spice parser for lower case device prefix.

2.6. 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.

2.7. V0.3.2 2017-02-22

  • fixed CCCS and CCVS

2.8. V0.3.1 2017-02-22

  • fixed ngspice shared

2.9. 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.
