Manual Variant Sink

Switch between multiple variant choices at output

• 

Libraries:
Simulink / Signal Routing

Description

The Manual Variant Sink block is a toggle switch that activates one of its variant choices at the output to pass the input.

The block can have two or more output ports and has one input port. Each output port is associated with a variant control. To change the number of output ports, right-click the block and select Mask Parameters, then type a value in the Number of choices box.

To toggle between the variant choices at output, double-click the block. The block displays the active choice with a line connecting the input to the output. The block propagates the active variant choice at output and discards the blocks connected to inactive output ports during simulation.

Note

• Double-clicking the Manual Variant Sink block does not open the block dialog box instead it toggles the output choice.

• Changing the active choice during compile, simulation, or paused states is not supported.

Examples

Provide Variation in Signal Source and Destination Using Manual Variant Source and Manual Variant Sink Blocks

Use the inline variant blocks Manual Variant Source and Manual Variant Sink. The Manual Variant Source Block provides variation on the source of a signal. The block is a switch that can have two or more input ports and one output port. Each input port is associated with a variant choice. Only one input port is active during simulation. The active input port determines the active variant region. Similarly, the Manual Variant Sink block provides variation on the destination of a signal. The block can have two or more output ports and one input port. Only one output port can be active during simulation, and the blocks connected to that port determine the active variant.

• Open Model

Variant Source and Variant Sink Blocks

Consider the slexVariantSourceAndSink model containing two Variant Source blocks Variant Source1 and Variant Source2, and a Variant Sink block. The variant conditions at the inports and the outports of the Variant Source and the Variant Sink blocks determine the activation and deactivation of the blocks connected to them. V and W are the variant control variables and are defined in the PostLoadFcn callback of the model.

Ports

Input

Port_1 — Input signal

scalar | vector

Input signal passed to the active output port.

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

Output

Port_1 — First variant output

scalar | vector

First variant output signal. The block passes the input signal to this output port when you connect the toggle switch to this port.

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

Port_n — nth variant output

scalar | vector

nth variant output signal. The block passes the input signal to this output port when you connect the toggle switch to this port.

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

Parameters

To access the block parameter, right-click the block and select Mask > Mask Parameters.
