The problem is that gpsim doesn't support the square wave stimulus too
well... A better approach is to use the 'asynchronous stimulus'. As a
good example, look at:
regression/digital_stim/digital_stim.stc
In CVS here:
http://cvs.sourceforge.net/viewcvs.py/gpsim/regression/digital_stim/digital_stim.stc?view=markup
There are two stimuli defined in there, one for for pulses and the other
for a step function.
