Stateflow® output data should not inherit properties from output signals, because the values back propagate from Simulink® blocks and can be unpredictable.
Avoid using machine-parented data. The presence of machine-parented data in a model prevents reuse of generated code and other code optimizations. This type of data is also incompatible with many Simulink and Stateflow features.
For example, the following features do not support machine-parented data:
Implicit change events
Detection of unused data
Model referencing (see Limitations on All Model Referencing in the Simulink documentation)
Analysis by Simulink Design Verifier™ software
Code generation by Simulink PLC Coder™ software
Parameters binding to a
in the base workspace
To make Stateflow data accessible to other charts and blocks in a model, use data store memory. For details, see Share Global Data with Multiple Charts.
