Adapter

Connect components with different interfaces

  • Adapter block

Description

The Adapter block allows you to connect the source and destination ports of components that have different interface definitions.

Adapter block

To add or connect System Composer™ components:

  • Add an Adapter block from the Modeling tab or the palette. The Adapter block has In and Out ports.

  • Click and drag a port to create a connection. Connect each port to another component. You can also create a new component to complete the connection.

  • Insert an Adapter block between two ports with different interfaces. You can create mappings between interface elements on each port.

To map between interfaces, apply interface conversions, and enter bus creation mode for architecture models:

  • Double-click the Adapter block to open the Interface Adapter dialog. In the dialog box, you can create and edit mappings between input and output interfaces, and set the Apply Interface conversion parameter to UnitDelay to break an algebraic loop or RateTransition to reconcile different sample time rates for reference models. When output interfaces are undefined, you can use input interfaces in bus creation mode to author owned output interfaces.

When you have Simulink® component behaviors with signal or message lines, then to merge message connections for architecture models and signal or message connections for software architecture models:

  • Manually configure the Adapter block by double-clicking the block to open the Interface Adapter. Set the Apply Interface conversion parameter to Merge.

  • For software architecture models, from the toolstrip, add a Merge block, which is a preconfigured Adapter block for merging.

Examples

Limitations

  • When used for structural interface adaptations, the Adapter block uses bus element ports internally and, subsequently, only supports virtual buses.

  • The Adapter block does not support mixing messages and signals as inputs and outputs.

  • When used in AUTOSAR architecture models, the names of corresponding input and output interface elements must match.

Ports

Input

expand all

If you connect to a source component, the interfaces on the ports should be compatible.

Output

If you connect to a destination component, the interfaces on the ports should be compatible.
