Hi Frank,

Yes that is correct. This one signal wouldn't trigger it at all on either level or edge. The signal was very narrow, about 5 ns, but I've had success with this type of signal before. I would guess that it won't repeat, because I've changed the code since then. I know it was triggering, because this particular signal was a write enable for a memory and the memory was filling up, even though signal tap couldn't trigger on it.

Regards,

Dan
