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
