Stateflow Design Summary
R2026bMetric ID
modeldesign.StateflowMaintainability[slcomp.DesignSummary]
Description
This metric returns a summary of maintainability measurements for the Stateflow® design layers in each unit. The summary includes the total number of design layers, state count, transition count, effective lines of code, and the accumulated Halstead difficulty and cyclomatic complexity across all Stateflow design layers in the unit.
Supported Artifacts
This metric collects metric results for Units in the project. To control what the dashboard classifies as a unit, see Categorize Models in Hierarchy as Components or Units.
Collection
To collect data for this metric, execute the metric engine with the metric ID.
metric_engine = metric.Engine;
results = execute(metric_engine,"modeldesign.StateflowMaintainability[slcomp.DesignSummary]")View the metric result values for a specific unit.
results(1).Value results(1).ScopeAlias
You can also collect all Stateflow maintainability metrics at once by using the group ID.
results = execute(metric_engine,"modeldesign.StateflowMaintainability[]")MetricID property of each result to identify which metric the result
belongs to.Results
The metric returns an array of metric.ResultValue property of the metric result object to view the metric
result values. Use the ScopeId and ScopeAlias
properties to identify which unit the result belongs to.
The ScopeAlias property returns the name of the unit.
The Value property returns a structure with these fields:
AccumulatedElements— Total number of Stateflow design layers in the unitStates— Total number of states across all Stateflow design layers in the unitTransitions— Total number of transitions across all Stateflow design layers in the unitHalsteadDifficulty— Accumulated Halstead difficulty across all Stateflow design layers in the unitComplexity— Accumulated cyclomatic complexity across all Stateflow design layers in the unitEffectiveLinesOfCode— Total effective lines of code across all Stateflow design layers in the unit
