Ports and Subsystems

Blocks related to subsystems, such as Inport, Outport, Subsystem, and Model

Use blocks from the Ports and Subsystem library to create input and output ports, as well as conditionally executed subsystems, iterator subsystems, and variant subsystems.

Blocks

Enable	Add enable port to subsystem or model
Enabled Subsystem	Subsystem whose execution is enabled by external input
Enabled and Triggered Subsystem	Subsystem whose execution is enabled and triggered by external inputs
For Each Subsystem	Apply algorithm to individual elements or subarrays of input signals or mask parameters
For Iterator Subsystem	Repeat subsystem execution during simulation time step for specified number of iterations
Function Element	Specify function to be called via exporting function port (Since R2022a)
Function Element Call	Specify function call to be issued via invoking function port (Since R2022a)
Function-Call Feedback Latch	Break feedback loop involving data signals between function-call blocks
Function-Call Generator	Provide function-call events to control execution of subsystem or model
Function-Call Split	Provide junction for splitting function-call line
Function-Call Subsystem	Subsystem whose execution is controlled by external function-call input
If	Select subsystem execution using logic similar to `if-else` statement
If Action Subsystem	Subsystem whose execution is enabled by If block
In Bus Element	Select input from external port
Inport	Create input port for subsystem or external input
Model	Reference another model to create model hierarchy
Out Bus Element	Specify output of external port
Outport	Create output port for subsystem or external output
Resettable Subsystem	Subsystem whose block states reset with external trigger
Subsystem	Group blocks to create model hierarchy
Switch Case	Select subsystem execution using logic similar to `switch` statement
Switch Case Action Subsystem	Subsystem whose execution is enabled by Switch Case block
Trigger	Add trigger or function port to subsystem or model
Triggered Subsystem	Subsystem whose execution is triggered by external input
Unit System Configuration	Restrict units to specified allowed unit systems
Variant Subsystem	Template subsystem containing Subsystem blocks as variant choices
While Iterator Subsystem	Repeat subsystem execution during simulation time step while logical expression is true
