Network Communication Project
A template is provided to initiate the modeling of Network Communication Matrices.
Project is structured as follow:
Network Communication Key Features
The Network Communication Project enables you to
- Author/edit communication matrices through tabular editor
- Define the matrix completely: frame, protocol data unit, bus signal, system signal
- Support the CAN family, LIN, FlexRay and Ethernet protocols
- Enable easy extensions for future new protocols
- Enable DBC file import
Creating Network Communication in detail
Creation of communication matrices elements are available from contextual menus “Create E/E Architecture Elements” invoked on and . Communication Matrices element
You can create communication matrices in the Matrices package which is shared with the purpose to reuse it in another project (e.g. System Mapping project).
To create communication matrix elements from the Matrices package
- In the Containment tree, right-click the Matrices package.
- From the shortcut menu, select Create E/E Architecture Elements and choose the needed one from the following:
- Communication Matrix
- System Signal
- System Signal Group
To create communication matrix elements from the Communication Matrices element
- In the Containment tree, right-click the Matrices package.
- From the shortcut menu, select Create E/E Architecture Elements and choose the needed one from the following:
- CAN Matrix
- Ethernet Matrix
- FlexRay Matrix
- LIN Matrix
You can also create dedicated Communication Matrix. To learn more about how to create matrices, see Creating diagrams.
