About Communication Matrices and System Signals

The Communications tab displays matrices and system signals.

• A matrix is a package that groups all the descriptions of the communications that occur on a multiplexed bus in the embedded architecture. It is structured as a list of data frames and individual bus signals. Matrices can be compliant with a standard. Such matrices have their description compatible with the AUTOSAR standard.
• The system signal concept is provided by AUTOSAR. This concept is used as a logical view of an end-to-end data flow through the architecture.

The Communications tab enables you to:

• Create new matrices. See Create Matrix. In these matrices, you can:
  • Create frames, PDUs, cyclic and burst events, bus signals, system signals, signal values, ...

    For more information, see Populating a Communication Matrix.

  • Import matrix description files compliant with existing industrial standards.

    For more information, see the EE Tools Section chapter.

• Edit the details of each object.
• Drag a bus signal from a frame to another frame of the same matrix.
