ahkab ===== **a SPICE-like electronic circuit simulator written in Python** The code should be easy to read and modify, the main language is Python -- 2 or 3 -- and it is platform-independent. News! ----- - Ahkab v0.18 was released on July 18 2015, including new features, bugfixes and improved documentation. It is recommended to upgrade. Check out `the release notes <https://github.com/ahkab/ahkab/releases/tag/v0.18>`__ for more! - The whole codebase has been going through a (yet incomplete) refactoring and documenting effort. The `new documentation is available on RTD <http://ahkab.readthedocs.org/en/latest/>`__. My resources are limited these days, so the much-needed work is proceeding slowly, albeit hopefully steadily. If you are interested and you would like to contribute to refactoring or documenting a particular feature, it would be very welcome. |Build Status| |Coverage Status| |PyPi version| |GPLv2 license| |DOI| Supported simulations: ---------------------- - Numeric: - **Operating point**, with guess computation to speed up the solution. See example: `Downscaling current mirror <https://ahkab.readthedocs.org/en/latest/examples/OP_simulation.html>`__ - **DC sweep** - **Transient analysis**, available differentiation formulas: implicit Euler, trapezoidal, gear orders from 2 to 5. See for example the `simulation of a Colpitts Oscillator <https://ahkab.readthedocs.org/en/latest/examples/Transient-Example.html>`__. - **AC analysis** - **PZ** analysis - **Periodic steady state analysis** of non-autonomous circuits, *time* *domain* shooting and brute-force algorithms. - Symbolic: - **Small signal analysis**, AC or DC, with extraction of transfer functions, DC gain, poles and zeros. Various `symbolic analysis examples on this page <https://ahkab.readthedocs.org/en/latest/examples/Symbolic-simulation.html>`__. The results are saved to disk, plotted or printed to stdout and can be read/processed by the most common tools (eg. `Octave <http://www.gnu.org/software/octave/>`__, `gnuplot <http://www.gnuplot.info/>`__, `Matlab <http://www.mathworks.com/products/matlab/>`__, `gwave <http://www.telltronics.org/software/gwave/>`__ and others) Install ------- The program requires: - the Python interpreter version 2 or 3 (at least v.2.6 for Python2, v.3.3 for Python3), - numpy>=1.7.0, scipy>=0.14.0, sympy>=0.7.6 and tabulate>=0.7.3. Matplotlib is strongly recommended and no plotting will work without. If you need more information about the dependencies, check the `Install notes <https://ahkab.readthedocs.org/en/latest/help/Install-Notes.html>`__. Usage ----- 1. ``ahkab`` can be run as a Python library ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. code:: python from ahkab import new_ac, run from ahkab.circuit import Circuit from ahkab.plotting import plot_results # calls matplotlib for you import numpy as np # Define the circuit cir = Circuit('Butterworth 1kHz band-pass filter') cir.add_vsource('V1', 'n1', cir.gnd, dc_value=0., ac_value=1.) cir.add_resistor('R1', 'n1', 'n2', 50.) cir.add_inductor('L1', 'n2', 'n3', 0.245894) cir.add_capacitor('C1', 'n3', 'n4', 1.03013e-07) cir.add_inductor('L2', 'n4', cir.gnd, 9.83652e-05) cir.add_capacitor('C2', 'n4', cir.gnd, 0.000257513) cir.add_inductor('L3', 'n4', 'n5', 0.795775) cir.add_capacitor('C3', 'n5', 'n6', 3.1831e-08) cir.add_inductor('L4', 'n6', cir.gnd, 9.83652e-05) cir.add_capacitor('C4', 'n6', cir.gnd, 0.000257513) cir.add_capacitor('C5', 'n7', 'n8', 1.03013e-07) cir.add_inductor('L5', 'n6', 'n7', 0.245894) cir.add_resistor('R2', 'n8', cir.gnd, 50.) # Define the analysis ac1 = new_ac(2.*np.pi*.97e3, 2.*np.pi*1.03e3, 1e2, x0=None) # run it res = run(cir, ac1) # plot the results plot_results('5th order 1kHz Butterworth filter', [('|Vn8|',"")], res['ac'], outfilename='bpf_transfer_fn.png') 2. ``ahkab`` can be run from the command line with a netlist file ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The syntax is: :: `$ python ahkab -o graph.dat <netlist file>` See ``ahkab --help`` for command line switches, `also online on the documentation pages. <http://ahkab.readthedocs.org/en/latest/help/Command-Line-Help.html>`__ Documentation ~~~~~~~~~~~~~ The `documentation is available on RTD <http://ahkab.readthedocs.org/en/latest/>`__. There, you can find a `documentation <http://ahkab.readthedocs.org/en/latest/ahkab.html>`__ and `examples <http://ahkab.readthedocs.org/en/latest/examples/Python_API.html>`__ regarding how to simulate from a Python script. Refer to the `netlist syntax page <http://ahkab.readthedocs.org/en/latest/help/Netlist-Syntax.html>`__ if you prefer to write netlist files that describe the circuit. Experience with running SPICE or related commercial simulators can be very useful: this is not for the faint of heart. Development model ~~~~~~~~~~~~~~~~~ - The development happens on the `github repository <https://github.com/ahkab/ahkab>`__, - Mostly on the master branch, with feature branch being created only for special purposes or non-trivial features. - Snapshots are released on a (hopefully) regular basis and are available on the `Releases pages, complete with changelog <https://github.com/ahkab/ahkab/releases>`__ and on `PYPI <https://pypi.python.org/pypi/ahkab/>`__ Patches and pull requests are welcome! How this project was born ~~~~~~~~~~~~~~~~~~~~~~~~~ This project was born when I was an enthusistic undergrad, apparently with plenty of free time, attending "Simulazione Circuitale" (*Circuit Simulation*) taught by `Prof. A. Brambilla <http://brambilla.dei.polimi.it/>`__ back in Italy at the Polytechnic University of Milan. I am grateful to prof. Brambilla for teaching one of the most interesting courses of my university years. -GV Bugs and patches ~~~~~~~~~~~~~~~~ Does it work? Bugs? Do you have patches? Did you run some noteworthy simulation? Let me know! Feedback is very welcome, my `email address <http://tinymailto.com/5310>`__ is available after a captcha. Support the development with a donation ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If you wish to support the development of ``ahkab``, ***please donate to cancer research:*** - `Association for International Cancer Research (eng) <http://www.aicr.org.uk/donate.aspx>`__, or - `Fond. IRCCS Istituto Nazionale dei Tumori (it) <http://www.istitutotumori.mi.it/modules.php?name=Content&pa=showpage&pid=24>`__. Credits ~~~~~~~ **Authors:** `Giuseppe Venturini <https://github.com/ggventurini>`__, with contributions from `Ian Daniher <https://github.com/itdaniher>`__ and `Rob Crowther <https://github.com/weilawei>`__. **Code:** the module ``py3compat.py`` is (c) 2013 - the Jinja team. **Dependencies:** many thanks to the authors of ``numpy``, ``scipy``, ``sympy``, ``matplotlib`` and ``tabulate``! .. |Build Status| image:: https://travis-ci.org/ahkab/ahkab.png?branch=master :target: https://travis-ci.org/ahkab/ahkab .. |Coverage Status| image:: https://coveralls.io/repos/ahkab/ahkab/badge.png?branch=master :target: https://coveralls.io/r/ahkab/ahkab?branch=master .. |PyPi version| image:: http://img.shields.io/badge/version-0.18-brightgreen.png :target: https://pypi.python.org/pypi/ahkab/ .. |GPLv2 license| image:: http://img.shields.io/badge/license-GPL%20v2-brightgreen.png :target: https://raw.githubusercontent.com/ahkab/ahkab/master/LICENSE .. |DOI| image:: https://zenodo.org/badge/doi/10.5281/zenodo.17696.svg :target: http://dx.doi.org/10.5281/zenodo.17696
