Description

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

A Manual Variant Source block can have two or more input ports and has one output port. Each input port is associated with a variant control. To change the number of input 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 input, 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 input directly to the output and discards the blocks connected to inactive input ports during simulation.

Note

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

Ports

Input

First variant input signal. The block passes this input signal to the 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

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