A DC signal is equivalent to 100% duty cycle. For example, a signal that overshoots to
4.2 V can only be at 4.2 V for 10.74% over the lifetime of the device; for device lifetime
of 10 years, this amounts to 10.74/10ths of a year.

(1) Figure 1–1 shows the methodology to determine the overshoot duration. In the example in Figure 1–1 , overshoot
voltage is shown in red and is present on the input pin of the Cyclone III device at over 4.1 V but below 4.2 V. From
Table 1–1 , for an overshoot 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.
