Features


development on linux




Known problems


Python 3 is not supported
PDF output is not perfect
no unittests




Basic usage
.. gtkwave:: docs/gtkwave_output.vcd


How it works
This is a workaround, there is no image export in GTKWave

start Xvfb headless X server using pyvirtualdisplay
redirect GTKWave display to Xvfb server by setting $DISPLAY variable.
start GTKWave with VCD file. Options are set on command-line and in temporary rc file
temporary tcl script will set time interval and select all signals
wait until GTKWave is displayed
take screenshot by pyscreenshot which needs scrot.
image is processed: toolbar, scrollbar and empty space are removed
use .. image:: directive to display image
