  20 Gwave is an analog waveform viewer which is used to view the output files produced by ngspice or gnucap.  Here are some feature suggestions.  You might choose a large handful of features to implement as your GSoC project.

  30 This project involves improving the integration of gwave into the
  31 interprocess-communication to and from the other tools, especialy gschem
  32 and gnucap.  While gwave has an X11-based remote mechanism, Dbus is now the
  33 standard, and should probably be used instead.

  43 Gwave has been ported to Gtk2.  As part of this effort, developing a battery of unit tests for gwave would be useful.  The idea is to create a variety of different input files which exercise gwave&#039;s ability to import and display waveforms.  An important feature for testing will be to compare the displayed waveform against a “golden” waveform to verify rendering correctness.
