Unused data, events, messages, and functions

Select the diagnostic action to take for detection of unused data, events, and messages in a chart. Removing unused data, events, and messages can minimize the size of your model.

Unexpected backtracking

Select the diagnostic action to take when a chart junction has both of the following conditions. The junction:

Invalid input data access in chart initialization

Select the diagnostic action to take when a chart:

No unconditional default transitions

Select the diagnostic action to take when a chart does not have an unconditional default transition to a state.

Transition outside natural parent

Select the diagnostic action to take when a chart contains a transition that loops outside of the parent state or junction.

Undirected event broadcasts

Select the diagnostic action to take when a chart contains undirected local event broadcasts.

Transition action specified before condition action

Select the diagnostic action to take when a transition action executes before a condition action in a transition path with multiple transition segments.

Read-before-write to output in Moore chart

Select the diagnostic action to take when a Moore chart uses a previous output value to determine the current state.

Absolute time temporal value shorter than sampling period

Select the diagnostic action to take when a state or transition absolute time operator uses a time value that is shorter than the sample time for the Stateflow block.

Self transition on leaf state

Select the diagnostic action to take when you can remove a self-transition on a leaf state.

Execute-at-Initialization disabled in presence of input events

Select the diagnostic action to take when Stateflow detects triggered or enabled charts that are not running at initialization.

Use of machine-parented data instead of Data Store Memory

Select the diagnostic action to take when Stateflow detects machine-parented data that can replace with chart-parented data of scope Data Store Memory.

Unreachable execution path

Select the diagnostic action to take when there are chart constructs not on a valid execution path.
