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.

Note to Table 1–2:  
(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.  
Figure 1–1 shows the methodology to determine the overshoot duration.
