Data Rise Time Percent Definition

Active Edge	Data Rise Time Percent
Not Applicable	It is the time difference from when a rising Data edge crosses the low threshold to when it crosses the high threshold. The high and low thresholds are percentage of the levels of the Data period to which the rising edge belongs.

Significance of statistics:
Mean	Not important.
Min	The min percent rise time should be more than the specified limit. Too small a percent rise time will induce noise on adjacent signal lines.
Max	The max percent rise time should be less than the specified limit. Too large a percent rise time will eat into the setup & hold times.
Peak cy-cy	Important. A higher cycle-to-cycle percent rise time indicates that the system is affected by noise or interference from adjacent signals or both.
Peak-to-peak	Not important.
