overshoot voltage is shown in red and is present on the input pin of the Cyclone IV
device at over 4.1 V but below 4.2 V. From
percentage of high time for the overshoot can be as high as 31.97% over a 10-year
period. Percentage of high time is calculated as ([delta T]/T) × 100. This 10-year
period assumes that the device is always turned on with 100% I/O toggle rate and
50% duty cycle signal. For lower I/O toggle rates and situations in which the device is
in an idle state, lifetimes are increased.
