example, overshoot voltage is shown in red and is present on the input pin of the
Cyclone III LS device at over 4.1 V but below 4.2 V. From
of 4.1 V, the 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 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.
