Reset
Add reset port to subsystem
- Library:
Ports & Subsystems
Description
A Reset block placed at the root level of a Subsystem block adds a control port to the block. When a reset trigger signal occurs on the signal connected to the port, the block states of the subsystem are reset to their initial condition.
Parameters
Reset trigger type — Select the type of trigger event
level (default) | rising | falling | either | level hold
Select the type of trigger signal that resets the subsystem block states.
levelReset the block states when the trigger signal is nonzero at the current time step or changes from nonzero at the previous time step to zero at the current time step.
risingReset the block states when the trigger signal rises from a zero to a positive value or from a negative to a positive value.
fallingReset the block states when the trigger signal falls from a positive value to zero or from a positive to a negative value.
eitherReset the block states when the trigger signal changes from a zero to a nonzero value or changes sign.
level holdReset the block states when the trigger signal is nonzero at the current time step.
Programmatic Use

| Type: character vector |
Value:
'level' | 'rising' |
'falling' | 'either' |
'level hold' |
Default:
'level' |
Propagate sizes of variable-size signals — Select when to propagate a variable-size signal
During execution (default) | Only when enabling
Select when to propagate a variable-size signal.
During executionPropagate variable-size signals at each time step.
Only when resettingPropagate variable-size signals when resetting a Subsystem block containing a Reset port block. When you select this option, sample time must be periodic.
