Drive a net with Signal Tap

My understanding is signal tap doesn't have the option of driving a net/pin, which would be very helpful. My question is why?! :) it's a neat feature and should be added IMO.

I can imagine a fast "SignalSource" tool as nice Quartus feature. It involves considerable extensions to the existing SignalTap II functionality, e.g. a waveform editor, stimulus trigger definition etc. I'm not sure if Altera is motivated to spend the development resources shortly. But I appreciate the suggestion.

SignalTap II is storing acquired data in internal RAM. It's not too complicated to implement a signal generator that replays stimuli from a RAM filled by the In-Memory-Content-Editor. The SignalTap II trigger output could start the signal generator. This should give the basic functionality you are asking for.
