Check usage of For Iterator blocks

Check ID: mathworks.hism.hisl_0008

Description

This check inspects the usage of For Iterator blocks.

Available with Simulink^® Check™.

Results and Recommended Actions

Condition Recommended Action

Condition	Recommended Action
The model or subsystem contains a For Iterator block that has variable iterations. This condition can lead to unpredictable execution times or infinite loops in the generated code.	For the identified For Iterator blocks, do one of the following: Set the Iteration limit source parameter to `internal`. If the Iteration limit source parameter must be `external`, use a Constant, Probe, or Width block as the source. Clear the Set next i (iteration variable) externally check box. Consider selecting the Show iteration variable check box and observe the iteration value during simulation.

Capabilities and Limitations

Does not run on library models.
Analyzes content of library linked blocks. By default, the input parameter Follow links is set to on.
Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to all.
Allows exclusions of blocks and charts.
