pyspice.py is a SPICE pre-processor written in Python, inspired by the Perl SPICE pre-processor spicepp by John Sheahan.
I developed this module as part of my own work and provide it here as a service
to the Python and SPICE communities. Additions, suggestions, and usefullness
reports are appreciated. It is currently licensed under the GPL.
It was (is currently being) developed with Python 2.4 and uses a few features introduced in 2.4. they relate to (re)sorting the netlist lines.
Updated 2006.11-11 (v0.2a):
- Each input "card" type has its own object type.
- Netlists are converted into an array of type instances.
- Netlist order is preserved for readability.
- Salient features of pyspice.py:
- Parallel capacitors are combined.
- Parallel MOSFETs are combined.
- Small capacitors are dropped for faster simulation.
Updated 2006.10.11 (v0.2):
- Fixed a missing newline so it doesn't throw an exception immediately, sorry.
Updated 2006.05.01 (v0.1)
- At least default (pass through) handling of all element types.
- NOTE: For combining, this uses a global node name scheme. In other
words: subcircuits, libraries, etc. are not in a separate node
namespace as they should be, beware.
- Changed structure of classes (in LEO), there are base classes
that contain common attributes and element classes that define the
- This version _should_ work with any netlist and only
touch M's and C's, YMMV.
- Work is ongoing on the class structure and most important IMO
is getting netlist hierarchy implemented.
The source is here. Usage (chmod +x):
I have been using
LEO to develop this, here is the .leo file.
- pyspice.py [options] [-i infile] [-o outfile]
- Use pyspice.py -h for all options.
And the requisite screenshot (v0.1):
