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 and overlapping adhere to recommended guidelines.
This check requires a Simulink Check™ license.
Check Parameterization
This check contains sub-checks that correspond to sub IDs specified in the MAB and JMAAB modeling guidelines. You can use the Model Advisor Configuration Editor to specify which sub IDs (one or multiple) to execute.
For reference, the MAB guideline sub ID(s) that are recommended for use by the NA-MAAB and JMAAB modeling standards organizations are:
NA-MAAB — a, b, c
JMAAB — a, b, c
Note
Subchecks db_0032_a, db_0032_b are selected by default.
Results and Recommended Actions
Guideline Sub ID | Condition | Recommended Action |
---|---|---|
db_0032_a: Check if signal lines are split into multiple sublines | 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
The subcheck db_0032_c cannot be executed on the model.
Considers signal hop preference.
Does not analyze block label overlaps.
Considers Simulink signals that split into more than two signals at a single branch.
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
.
