To simplify model appearance, combine individual signals into composite signals using these techniques:
Virtual buses
Nonvirtual buses
Mux signals
Concatenated signals
For a detailed comparison of composite signals, see Types of Composite Signals.
Virtual buses meet most modeling requirements for combining signals into a composite signal and give you flexibility for combining different types of signals.
Bus Editor | Create, modify, and manage Simulink.Bus objects |
Model Explorer | View, modify, and add elements of Simulink models, Stateflow charts, and workspace variables |
Reduce visual complexity in a model by combining signals into a composite signal.
Identify the blocks that support virtual buses, nonvirtual buses, and arrays of buses.
Group Signal Lines into Virtual Buses
Combine signals into virtual buses, which only affect visual appearance.
Simplify Subsystem and Model Interfaces with Buses
Use In Bus Element and Out Bus Element blocks for bus inputs and outputs.
Display information about buses, such as signal hierarchy and whether the bus is virtual or nonvirtual.
Identify Automatic Bus Conversions
Recognize modeling patterns that cause hidden Bus To Vector and Signal Conversion blocks.
Change the order and hierarchy of nested buses and their elements.
Replace Values of Bus Elements
Use a Bus Assignment block to assign values to elements of a bus.
Specify Initial Conditions for Bus Elements
Specify bus element values as initial conditions for buses.
Share and Reuse Bus-Routing Blocks
Share blocks that create or interact with buses using subsystem references or custom libraries.
Specify Bus Properties with Simulink.Bus Object Data Types
Understand Simulink.Bus
object uses and
implementation.
Create Bus Objects Programmatically
Use functions and classes to define Bus
objects and bus
elements, create bus objects from blocks, or create Bus
objects
from MATLAB® data.
Customize Bus Object Import and Export
Customize the Bus Editor import and export commands by writing MATLAB functions that provide the desired capabilities. Register these functions using the Simulink® Customization Manager.
Create buses that appear in generated code and support modeling constructs such as arrays of buses.
Modify Sample Times for Nonvirtual Buses
Make the sample time of signals the same so that you can group them in a nonvirtual bus.
Generate Code for Nonvirtual Buses
Use a structure in code generation to represent a nonvirtual bus. Control data types of initial condition structure fields.
Inspect Generated Code for Nonvirtual Buses
Find nonvirtual buses in generated code for a simple model.
Group Nonvirtual Buses in Arrays of Buses
Streamline a model by combining nonvirtual buses that have the same data type into an array.
Set up your model to use an array of buses to select signals, assign values to a signal, perform iterative processing, log and load signals, and initialize signals.
Convert Models to Use Arrays of Buses
Convert an existing model that does not use arrays of buses to use arrays of buses.
