Hi! In Specctrquest in order to do flight time calculation I am using Buffer Delay: On the Fly. Now for the stimulus is it better to use a random data pattern or just pulses for address/data bus. I know for address bus it is much better to use random pattern in order to generate EYE mode but what if I am interested in Flight time. When I look at the Switch time Fall/Rise with pulse stimulus it is 0.25ns but with random pattern it is 2.5ns. What would be a close approximation for Flight time number? Thanks in advance Bob __________________________________________________ Do You Yahoo!? Make a great connection at Yahoo!
