복합 신호 기본 사항

Types of Composite Signals

Reduce visual complexity in a model by combining signals into a composite signal.

버스 기본 사항

Group Signal Lines into Virtual Buses

Combine signals into virtual buses, which only affect visual appearance.

Display Bus Information

Display information about buses, such as signal hierarchy and whether the bus is virtual or nonvirtual.

Bus-Capable Blocks

Identify the blocks that support virtual buses, nonvirtual buses, and arrays of buses.

Simplify Subsystem and Model Interfaces with Buses

Use In Bus Element and Out Bus Element blocks for bus inputs and outputs.

Modify Bus Hierarchy

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.

Identify Automatic Bus Conversions

Recognize modeling patterns that cause hidden Bus To Vector and Signal Conversion blocks.

Share and Reuse Bus-Routing Blocks

Share blocks that create or interact with buses using subsystem references or custom libraries.

Trace Connections Using Interface Display

Display interfaces to trace signals through the nested levels, annotate signal characteristics, and view units associated with signals.

Bus 객체

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.

비가상 버스

Create Nonvirtual Buses

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.

Use Buses at Model Interfaces

버스 배열

Group Nonvirtual Buses in Arrays of Buses

Streamline a model by combining nonvirtual buses that have the same data type into an array.

Requirements of Arrays of Buses

Work with Arrays of Buses

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.
