PySpice 1.0.0

Simulate electronic circuit using Python and Ngspice simulator

---

Overview

What is PySpice ?

In short PySpice is an open source Python module which interface Python and the famous Spice circuit simulator.

Mainly it permits:

• to define a circuit, so called netlist,

• to perform a simulation using Ngspice,

• to analyse the output using Numpy and Matplotlib

Where is the Documentation ?

The documentation is available on the PySpice Home Page.

How to install it ?

Look at the installation section in the documentation.

News

V1.0.0

• 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

V0.4.2

• Fixed Spice parser for lower case device prefix.

V0.4.0

• 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

• fixed CCCS and CCVS

V0.3.1

• fixed ngspice shared

V0.3.0

• 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.
