Check signal line connections

Check ID: mathworks.jmaab_v6.db_0032

Guideline: db_0032: Signal line connections

Description

Checks if the Simulink® signals that are intersecting or overlapping adhere to the following guidelines.

  • Signals lines do not split into more than two signal lines at a single branch point.

  • Signal lines are drawn as vertical or horizontal lines.

This check requires a Simulink Check™ license.

Check Parameterization

This check contains sub-checks that correspond to sub IDs specified in the JMAAB modeling guidelines. You can use the Model Advisor Configuration Editor to specify which sub IDs (one or multiple) to execute.

For reference, the guideline sub ID(s) that are recommended for use by the JMAAB modeling standards organizations are:

  • JMAAB — a, b

Note

Subchecks db_0032_a and db_0032_b are selected by default.

Results and Recommended Actions

Guideline Sub IDConditionRecommended Action
db_0032_a: Check if signal lines are split into multiple sub lines.Signal lines are split into more than two signal lines at a single branch point.Reposition signal lines to avoid splitting into more than two signal lines at a single branch point.
db_0032_b: Check if signals are drawn as slanting lines.Signal lines are drawn as slanting lines in the diagram.Draw signals as vertical or horizontal lines.

Capabilities and Limitations

  • Does not support detection of signal lines that bend multiple times unnecessarily, as described in sub ID c of the JMAAB modeling guidelines.

  • Considers Simulink signal lines that split into more than two signal lines at a single branch point.

  • Runs on library models.

  • Allows exclusions of subsystems.

  • 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 graphical.
