simplifyInterfacesWithBusPorts

Update model or subsystem file to use bus element ports for buses

Since R2025a

Syntax

simplifyInterfacesWithBusPorts(file)

Description

simplifyInterfacesWithBusPorts(file) updates the model or subsystem file specified by file to use bus element ports for buses at the model and subsystem interfaces. The bus element ports replace input or output ports that connect to Bus Selector or Bus Creator blocks.

The function does not update referenced model interfaces.

Examples

Update Model to Use Bus Element Ports

To simplify your block diagram, replace input port blocks that connect to Bus Selector blocks and output port blocks that connect to Bus Creator blocks. To select bus elements at a model or subsystem interface, use In Bus Element blocks. To group elements into buses at a model or subsystem interface, use Out Bus Element blocks.

Open a model that contains:

• Bus Selector blocks connected to Inport blocks

• Bus Creator blocks connected to Outport blocks

To display bus line styles, update the model.

openExample("simulink_features/SimulinkBusCapabilitiesExample")

Navigate to a subsystem that shows Bus Selector and Bus Creator blocks at subsystem interfaces. In this example, navigate to the PortConversion subsystem that displays content previews on two Subsystem blocks. One Subsystem block outputs a bus that the other Subsystem block receives.

open_system("BusCapabilities/PortConversion")

Update the model to use bus element ports for buses at the model and subsystem interfaces.

simplifyInterfacesWithBusPorts("BusCapabilities")

Input Arguments

file — Model or subsystem file

filename

Model or subsystem file, specified as a filename.

When you specify a filename, omit the file extension.

Example: simplifyInterfacesWithBusPorts("mymodel")

Data Types: double | char | string

Tips

• To convert one port at a time, see createBusPort.

• To convert ports interactively, see Simplify Subsystem and Model Interfaces with Bus Element Ports.
