-

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 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 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

    • -
-
-
-
-

V1.0.0 2017-09-06

-
-
    -
  • Bump version to v1.0.0 since it just works!
    • -
  • Support Windows platform using Ngspice shared mode
    • -

    • -
  • 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.
