1 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 shows the methodology to determine the overshoot duration. The
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 Table 1–2, for an overshoot of 4.3 V, the
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.
