DDS Blockset

Design and simulate DDS applications

DDS Blockset provides apps and blocks for modeling and simulating software applications that publish or subscribe to Data Distribution Service (DDS) middleware. The blockset includes a DDS dictionary that lets you manage, create, and edit your DDS definitions in Simulink^®. You can import DDS specifications as XML files to create a skeleton Simulink model as a starting point for developing algorithms for DDS applications.

DDS Blockset provides blocks for publishing and subscribing samples to DDS, including their corresponding Quality of Service (QoS.). It fully integrates with the RTI Connext DDS and eProsima Fast DDS stacks.

DDS Blockset generates C++ code and XML files from Simulink models (with Embedded Coder^®).

Modeling DDS Applications

Model and simulate applications that use the DDS middleware protocol and Quality of Service (QoS) policies.

Create DDS Applications

Use the DDS Application Quick Start app to create default DDS definitions or use predefined DDS definitions created in DDS Simulink models. You can configure DDS models as Publishers and Subscribers to DDS Topics using preconfigured blocks.

Configure and Manage DDS Definitions

View and manage DDS definitions including Domains, Topics, Types, and QoS for DDS applications using the DDS dictionary. Additionally, you can use the code mappings editor to configure a DDS interface to specify the Topic and QoS for the DataReader and DataWriter entities of your application.

Simulating DDS Applications

Simulate DDS Simulink models including their QoS.

Simulate DDS Models and QoS

Simulate DDS models configured as Publishers and Subscribers to DDS Topics and Quality of Services (QoS) including HISTORY to verify the runtime behavior with specified QoS policies.

Importing and Exporting DDS Descriptions

Develop DDS applications in Simulink. Start with a Simulink model or import DDS definitions as XML files.

Starting with a Simulink Model

Create and model DDS applications in Simulink using the DDS Application Quick Start app. Build your application model to export DDS definitions as XML files for RTI Connext and IDL files for eProsima with Embedded Coder.

Starting with DDS Definitions from an XML File

You can import DDS definitions from third-party generated XML files into Simulink using DDS Application Quick Start. This approach enables you to bring DDS concepts such as Domains, Topics, Types, and QoS into Simulink for DDS applications.
