Definition: |
This element represents a logical state transition that occurs within a Waveform <waveform> at a specified time. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Remarks: |
An optional edge identifier can be specified using the "id" attribute. This identifier is required if this Edge will be referenced by relationship elements. The Edge element contains optional attributes to specify state (the "s" attribute) as well as time (the "te" attribute and the "tl" attribute). These should be used in the following ways: The initial state of a Waveform <waveform> (the state at time minus infinity) may be specified using only the state attribute ("s") in the first Edge of the Waveform <waveform>. This Edge should not have any time attributes ("te" or "tl") The last Edge in a Waveform <waveform> can be used to specify the time to which the waveform extends after the last transition. In this case the Edge would be specified with time attributes ("te" and/or "tl") and no state attribute ("s"). Transitions that have a single distinct transition time are specified using the state attribute ("s") along with the time attribute "te". Transitions whose transition time is uncertain are specified using the state attribute ("s") along with both the time attributes ("te" and "tl"). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
