Element: | Uncertainty Falling |
Tag: | <uncertainty.falling> |
Definition: |
Uncertainty Falling is the amount of time starting from the falling Edge <e> of a clock during which the Edge <e> transition may occur. For example, if a falling clock transition occurred at 50ns and had 10ns of Uncertainty Falling, then the transition could occur at any time from 50ns to 60ns. This type of uncertainty results when a clock Signal <signal> propagates through interconnect delays or buffer delays whose delay times are specified as a range of possible times. This element is used to describe uncertainty in clock type Signals <signal>s. Uncertainty on edges of other types of signals are determined by the "te" attribute and the "tl" attribute on the Edges <e>s. The Jitter Falling <jitter.falling> element is similar to this element, but it models a different physical phenomenon where the uncertainty is centered around a falling transition instead of starting from the transition. |
