gEDA-user: simulation data reader

2011-04-04 Thread Dan White
Built with the help of the latest SVN of gwave's libspicefile (sp2sp) utility, I use an in-house system to read simulation data into python as a numpy array with attributes. Data files are translated with sp2sp to the numpy np.save()/load() ".npy" format and read in as mem-mapped arrays to gracefu

gEDA-user: gnucap, hspice output -> python

2011-01-20 Thread Dan White
There have been a few python-based tools for analysis of simulation data posted here, e.g. "oscopy" and "dataplot". Here is another to complement them. To use python and numpy's arrays as the working format for signal analysis requires conversion or import from a simulator's usual output. Current

gEDA-user: series of gnetlist backend patches

2011-01-02 Thread Dan White
I've pushed my local changes to the spice-sdb gnetlist backend and a new backend out to repo.or.cz and also on the SourceForge patch tracker. These have been part of my workflow for gschem -> {gnucap-arails, hspice} within my analog VLSI work for some time. The holidays presented time to clean the

gEDA-user: sch2sym.py and Makefile example

2009-10-06 Thread Dan White
I have begun to use gaf for an audio prototyping board for a University course I'm teaching. The gEDA site claims no schematic-to-symbol generator so I rolled my own and am making the first-pass available to start to fill the gap. I am been using the gEDA Binary Suite 0.0.2 for the moment until I
