VHDL will only stop executing when either ther are no more scheduled signal updates or execution time maxes out.

ghxl The automatic invocation of the gtkwave app by clicking on files is one. Fate Jun 12 ’13 at It’s only known to run on OS X Obtaining Tony Bybell’s gtkwave gtkwave.

In the signals window select a[3: A ghw file can be clicked on and gtkwave has a set of rules used to search for the applicable gtkw file. In the title of the gtkwave it just says GTKWave – [no bhdl loaded]. The only real difference in my example is using the ghw waveform format.
