Check usage of Memory and Unit Delay blocks
Guideline: jc_0623: Usage of continuous-time Delay blocks and discrete-time Delay blocks
Checks Memory and Unit Delay blocks with inappropriate sample time.
This check identifies these conditions:
Memory blocks with a discrete sample time.
Delay and Unit Delay blocks with a non-discrete sample time.
This check requires a Simulink® Check™ and Stateflow® license.
This check does not include sub-checks because the MAB modeling guideline provides only one sub ID.
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
JMAAB — a
Results and Recommended Actions
|Memory blocks have sample time that is not continuous.||Use Unit Delay block instead of Memory block.|
|Unit Delay blocks have non-discrete sample time.||Use Memory block instead of Unit Delay block.|
Capabilities and Limitations
Analyzes content of library-linked blocks. By default, the input parameter Follow links is set to
Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to
Allows exclusions of blocks and charts.
