Display model metrics and complexity report
Display number of elements and name, level, and depth of subsystems for the model or subsystem.
The IEC 61508, ISO 26262, EN 50128, and EN 50657 standards recommend the usage of size and complexity metrics to assess the software under development. This check provides metrics information for the model. The provided information can be used to inspect whether the size or complexity of the model or subsystem exceeds given limits. The check displays:
A block count for each Simulink® block type contained in the given model, including library linked blocks.
A count of Stateflow® constructs in the given model (if applicable).
Name, level, and depth of the subsystems contained in the given model (if applicable).
The maximum subsystem depth of the given model.
Available with Simulink Check™.
This check requires a Stateflow license.
