Description

The Resettable Subsystem block is a Subsystem block preconfigured as a starting point for creating a subsystem that resets the block states each time the control port receives a trigger signal.

Ports

Input

In — Signal input to a subsystem block

scalar | vector | matrix

Placing an Inport block in a Subsystem block adds an external input port to the block. The port label matches the name of the Inport block.

Use Inport blocks to receive signals from the local environment.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus

Reset — Control signal input to a subsystem block

scalar | vector | matrix

Placing a Reset block in a Subsystem block adds an external input port to the block and changes the block to a Resettable Subsystem block.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point

Output

Out — Signal output from a subsystem

scalar | vector | matrix

Placing an Outport block in a Subsystem block adds an output port from the block. The port label on the Subsystem block is the name of the Outport block.

Use Outport blocks to send signals to the local environment.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus

Discrete and Continuous Resettable Subsystems

The comparison between behaviors of discrete and continuous resettable subsystems. After running the simulation, the two scopes show the results for the discrete resettable subsystem (top scope), and continuous enabled subsystems (bottom scope).
