The critical data http://www.moreviews.net entered into a timing diagram is the delay times and operating constraints of the system components. These timing parameters are generally expressed as a range (e.g. 5-10 ns) because there is some uncertainty http://www.moreviews.net associated with high volume component manufacture and circuit operating conditions. To combat these uncertainties in component delays and constraints, designers have traditionally been forced to http://www.moreviews.net assume worst case operating conditions that are overly pessimistic with regard to maximum operating speed. This is because the probabilities associated with these ranges are generally treated as independent quantities.
