Signal Routing

R2026b

Blocks for routing and organizing signals, such as Bus Creator, Selector, and Switch

Use blocks from the Signal Routing library to control how signals flow between blocks in your model. You can create composite signals, split and merge signal paths, store and retrieve shared data, and switch between input sources based on conditions.

To add blocks from this library to your model, see Add Blocks to Models.

Blocks

	Bus Assignment	Assign new values to specified bus elements
	Bus Creator	Group input signals, buses, or messages into bus
	Bus Selector	Select elements from input bus
	Data Store Memory	Define data store
	Data Store Read	Read data from data store
	Data Store Write	Write data to data store
	Demux	Extract and output elements of virtual vector signal
	Environment Controller	(Removed) Create branches of block diagram that apply only to simulation or only to code generation
	From	Accept input from Goto block
	Goto	Pass block input to From blocks
	Goto Tag Visibility	Define scope of Goto block tag
	Index Vector	Switch output between different inputs based on value of first input
	Manual Switch	Switch between two inputs
	Manual Variant Sink	Switch between multiple variant choices at output
	Manual Variant Source	Switch between multiple variant choices at input
	Merge	Combine multiple signals into single signal
	Multiport Switch	Select output signal based on control signal
	Mux	Combine input signals of same data type and complexity into virtual vector
	Parameter Writer	Write to block parameter or variable
	Selector	Select input elements from vector, matrix, or multidimensional signal
	State Reader	Read a block state
	State Writer	Write to a block state
	Switch	Switch output between first input and third input based on value of second input
	Variant End	Define end of bounded region (Since R2024a)
	Variant Sink	Route amongst multiple outputs using variants
	Variant Source	Route among multiple inputs using variants
	Variant Start	Define start of bounded region (Since R2024a)
	Vector Concatenate	Concatenate input vectors of same data type for iterative processing
