A DC signal is equivalent to 100% duty cycle. For example, a signal that overshoots to
4.3 V can only be at 4.3 V for 65% over the lifetime of the device; for a device lifetime
of 10 years, this amounts to 65/10ths of a year.

Figure 1–1
overshoot voltage is shown in red and is present on the input pin of the Cyclone IV
device at over 4.3 V but below 4.4 V. From
percentage of high time for the overshoot can be as high as 65% 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.
