Spyce, Simple python circuit editor

A simulink like editor with MyHDL netlist support. Heavily borrowed from a project for pycontrol by Roberto Bucher http://robertobucher.dti.supsi.ch/python/ for the SUPSI university. You will find some references to supsi :) and maybe some remaining packages that we did not yet update or remove

The following packages should be installed on your PC

pyenv (https://github.com/pyenv/pyenv) if you want an environment with any non-default python version. Highly recommended!
Python 2.7+ or Python 3.5+ (best via pyenv)
PySide, PySide2, PyQt4 or PyQt5
Qt.py wrapper around PySide, PySide2, PyQt4 or PyQt5(see https://github.com/mottosso/Qt.py)
MyHDL (best with fixbv extension, see https://github.com/imec-myhdl/myhdl)
LateX if you want to build the pdf documentation
our setup is based on python 3.8.1 and PySide2

Installing as normal user:

Install Spyce (checkout with git)

   git clone https://github.com/imec-myhdl/Spyce.git

install the dependencies with pip (assuming you are on python3):

   pyenv shell 3.8.1    # select your environment
   pip install pyside2  # python interface to Qt5
   pip install Qt.py    # thin wrapper around PyQt3/5 Pyside/Pysisde2
   pip install autopep8 # format block sources (on disk) conform pep8
   pip install svgwrite # interface to inkscape
   pip install lxml     # legacy blocks, will gradually be phased out

Workspace preparation

   mkdir workdir
   cd workdir
   
   # optional: create settings.py
   # use this file to make local modifications to the defaults (in spycelib/const.py)

Editor (standalone)

To start the editor you do not need a setup/make step. You can run it can directly without installing.

cd workdir
python <path-to-spyce>/Spyce/BlockEditor/spyce.py

# or define an alias (e.g. in your ~/.bashrc):
alias spyce='python <path-to-spyce>/Spyce/BlockEditor/spyce.py'
cd workdir
spyce

Documentation (standalone)

cd <path-to-spyce>/Spyce/doc
make latexpdf # or make html whatever you prefer and is supported by sphinx

manual will be in build/latex/spyce.pdf

Warning:

Dangerous software, do not run as superuser, and be aware that there are bugs that could cause lost work (save as wrong filename for example). UNDO function is not implemented.
