Timing Group
The Timing group is used solely for Timing diagrams, which use a time-scale to define the behavior of objects. The time-scale visualizes how the objects change state and interact over time.
Timing diagrams can be used for defining hardware-driven or embedded software components, and time-driven business processes.

Usage |
A Lifeline is the path an object takes across a measure of time, indicated by the x-axis. A State Lifeline follows discrete transitions between states, which are defined along the y-axis of the timeline; any transition has optional attributes of timing constraints, duration constraints and observations. A Value Lifeline shows the lifeline's state across the diagram, with parallel lines indicating a steady state; a cross between the lines indicates a transition or change in state. To add an element to the current diagram, click on the required icon and drag it into position on the diagram; set an element name and other properties as prompted. To add a relationship, click on the required icon, then click on the start element in the diagram and drag to the end element.
