| + | ==== Gwave -- analog waveform viewer ==== | ||
| + | |||
| + | 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. | ||
| + | |||
| + | |||
| + | == gEDA integration == | ||
| + | |||
| + | This project involves improving the integration of gwave into the | ||
| + | interprocess-communication to and from the other tools, especialy gschem | ||
| + | and gnucap. While gwave has an X11-based remote mechanism, Dbus is now the | ||
| + | standard, and should probably be used instead. | ||
| + | |||
| + | == Developing unit tests for GTK+-2.0 == | ||
| + | |||
| + | 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'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. | ||
| + | |||
| + | == User Interface == | ||
| + | |||
| + | * Replace the existing variable-list with a tree-style variable-selector. allow multiple ways of organizing the tree: file/sweep/variable vs. file/variable/sweep, extract circuit heirarchy from variable names, etc. Perhaps a two-pane tree browser, with the internal nodes of the tree in one pane, and the leaf nodes (variables that can be displayed) in another. | ||
| + | * Add icons to the toolbar elements | ||
| + | * Enhance use of Gtk2.0 file chooser: wildcards for selecting particular types of files, | ||
| + | * Accept drag-and-drop from a file manager to add files, run scripts | ||
| + | * Allow drag-and-drop from one wavepanel to another to move wave | ||
| + | * Remember/restore the position of the windows, both most-recent-session, and also save it in the scripts. | ||
| + | * Add keybinding mechanism | ||
| + | * An undo stack for operations that change the view | ||
| + | * Add a guile console window, where expressions can be typed to query/manipulate/debug gwave objects and variable data. | ||
| + | |||
| + | == Data visualization and analysis == | ||
| + | |||
| + | * Draw a real graticule in wave panels, including a grid of faint/dotted lines and numeric scales | ||
| + | * Add ability to customize measurements | ||
| + | * Add additional drawing styles: dotted/dashed lines, symbols showing actual datapoints, | ||
| + | * Add user-configurable colors | ||
| + | * waveform calculations (Requires some of the infrastructure work below) | ||
| + | * display-functions of a single wavevar and scalars | ||
| + | * display-functions of wavevars sharing the same independent var | ||
| + | * more general stuff that computes a new wavevar | ||
| + | * Additional types of wavepanels for different types of viewing/analsis. (best done after refactoring the wavepanel UI elements into a class heirarchy of proper Gtk widgets) | ||
| + | |||
| + | == Datafile/Variable Infrastructure == | ||
| + | |||
| + | * Readers for additional file-formats: wdf, sst2, psf have been mentioned | ||
| + | |||
| + | * Convert from ad-hoc data structures to a glib/GObject class heirarchy | ||
| + | |||
| + | * Ability to add a variable to a file after it is read in, to support computing a new variable as a function of existing ones | ||
| + | |||
| + | * Deferred read: initialy read only the independent variable from a datafile, then read the others when they are first displayed. | ||
| + | |||
| + | * Add a new class of variable, which is a function of other variables and constants to computed on the fly as it is displayed | ||
| + | |||
| + | * New class of variable for digital data; reader and display capability for verilog vcd | ||
| + | |||
| + | * Ability to create new datafile-like constructs programaticly, to hold the result of computations involving variables in two or more exisiting files. | ||
| + | |||
| + | * Handle creation of the independent-variable intelligently. | ||
| + | |||
| + | == Other infrastructure == | ||
| + | |||
| + | * convert other data structure from ad-hoc structures wrapped as custom SMOBs to GObject wrapped with guile-gobject. | ||
| + | |||
| + | * Convert the wavepanel drawing-area code into a new Gtk widget type | ||
| + | |||
