Flowchart View

The Flowchart shows various states possible and transitions between them. States and transitions
found are visually differentiated from those that are not found in current trace. For example, states
and transitions not found are grayed out. When a state is selected in the Box Car view, the
corresponding state bubble is selected in the Flowchart view along with the state transition that
caused the state change. Both the state and transition are identified by a thicker border/arrow.
Similarly, when an event is selected in the main event grid, the state bubble corresponding to the
selected event in the Flowchart view and state box in Box Car view are highlighted.
Invalid states are displayed with a red border. Counts are shown for each state or transition that is
not grayed out.
There are three different views for the Flowchart view. One is Overall view. In this view, all the
main states are shown. When the selection in Box Car view is a main state, or the selected event in
event grid corresponds to a main state, this Flowchart view is displayed.
Figure 165: Flowchart View (Overall View)
Some of the states, Configuration and Recovery, have sub-states. When selection in Box Car view
is a sub-state, or a selected event in event grid corresponds to a sub-state, the Flowchart view
shows one of the following diagrams. Transitions and states/sub-states are grayed out based on
availability. These flowcharts are as described in PCIe specifications.
