Rule

Sub ID a

Block parameter Sample time shall be set to -1 (inherited).

Exceptions

Inport block
Outport block
Atomic subsystem
Blocks with state variables, such as Unit Delay and Memory
Signal conversion blocks, such as Data Type Conversion and Rate Transition
Blocks that do not have external inputs, such as Constant
Stateflow charts

Custom Parameter

Not Applicable

Rationale

Sub ID a:

Discrepancies can occur in the processing of the model because of different simulation times.
Maintainability of the model deteriorates when a specific sample time is set for each block individually.

Verification

Model Advisor check: Check for sample time setting (Simulink Check)
