You got a stimulus file to work? The setup seems easy enough, but my watch window just showed zeros being read in. I sent a fax to tech support but never heard back. What steps did you take to get it to work?

I'm working on a serial communication receiver and the timing is very critical in this application. It would be great to specify time in uS or nS for when you want a certain stimulus activated rather than converting that time (as closely as possible) into STEPS. Is this possible in any way? Hamilton
