Scheduling model components for simulation or integration with an external scheduler requires the algorithms to be placed in Atomic Subsystem or Model blocks. The execution rate is then specified as either periodic (scheduled subsystem) or nonperiodic (function-call subsystem).
Partitions are components of a model that execute independently as atomic tasks. In multitasking models, partitions are created from model components. With partitions, you can separate parts of the model that you can explicitly control in the Schedule Editor tool.
The Schedule Editor is a scheduling tool that represents the components in the model known as partitions, the data connections between them, and the ordering of those partitions. The Schedule Editor can only be used on existing components, such as atomic subsystems, export functions, and model blocks. The Schedule Editor is an interactive tool that provides an easy way to view and edit the schedule of the model components.
|Function-Call Subsystem||Subsystem whose execution is controlled by an external function-call input|
|Function-Call Generator||Provide function-call events to control execution of a subsystem or model|
|Function-Call Split||Provide junction for splitting function-call line|
|Function-Call Feedback Latch||Break feedback loop involving data signals between function-call blocks|
|Trigger||Add trigger or function port to subsystem or model|
