Communication Concepts: Current Development

"Service-orientation in E/E designs" (26 min.). Part 1/2 about SOA fundamentals and CANoe´s support for SOA testing of vehicle networks.

The classic signal-based communication is increasingly supplemented by service-oriented communication patterns. The AUTOSAR Adaptive platform, for example consistently uses service-oriented approach. Service-oriented communication is often based on the TCP/IP protocol stack and uses communication middleware, for example SOME/IP. The transmitted network message, i.e. the Ethernet frame, and the actual application view drift here much more apart than in case of signal based communication via CAN. In addition, the service interfaces and the associated data structures are defined in a way which is detached from a specific network transmission or network topology.

... and CANoe´s Communication Model

Graphic of CANoe´s communication model
Communication model of CANoe

CANoe supports this new design paradigm. To do so, databases are imported into the CANoe communication model. Via a built-in communication object editor you can define your own communication objects and edit the existing ones.

"How to test SOA applications with CANoe" (25 min). Part 2/2 about SOA fundamentals and CANoe´s support for SOA testing of vehicle networks.

CANoe enables the use of the service interfaces directly as modeling artifact. The service interfaces support methods and events. Complex data types, used for example in the area of object detection, are supported directly. Endpoints which provide or use a service interface (providers and consumers) can be directly simulated in CANoe.

Full control over all relevant log data consists in the simulation. In addition, sophisticated error detection mechanisms facilitate the debugging of the system.

The physical connection to the sensor networks is done using the hardware module VT2710. It is fully adapted to the functionality of CANoe.Sensor and part of Vector's modular test environment VT System. The flexible structure of the VT2710 is beneficial: as required, up to four PSI5 or SENT channels are configurable with piggybacks. With this module, users have a precise analysis tool, which allows accurate bitrate settings and precise message time stamps and fits in seamlessly into the existing VT environment with the tool concept as well as the programming interface. The module is prepared for additional sensor logs.

CANoe Options for Aerospace

Option A429

CANoe .A429 Screenshot including some analysis and simulation windows

CANoe.A429 is ideal for the test and analysis of ARINC 429 buses and of individual devices on up to 32 channels. Regardless of whether raw data or physical quantities are required – CANoe.A429 provides powerful analysis functions on all levels. Users reach their goals quickly and also get a clear overview in complex network constellations.


Overview of Advantages

  • Reliable testing of data communication – from simple interactive tests to systematic automated tests
  • Automatically create test protocols
  • Easy monitoring of the data traffic and comprehensive network analysis
  • Just a single tool for accessing CAN, AFDX® and the Vector VT System, a modular test environment
  • Detect and correct error situations early in the development process


Symbolic Representation

ARINC 429 words for a bus can be described in a database. This involves assigning readable names to the ARINC 429 labels, and the data contents of the ARINC 429 words are also defined in detail. This not only includes the bit position within the ARINC 429 word, but also the data type and display name. For an interpreted display of physical parameters, you can also enter the units and define a conversion formula. A Database Editor is included with the product.


Display of Messages

The Trace Window lists the momentary ARINC 429 bus traffic clearly. When databases are available, the representation is symbolic – conversion formulas are automatically used. The layout of columns is user configurable, and three preconfigurable column layouts are available for quick toggling of the display. Refined search functions ensure that the user can quickly find all relevant information, even in cases of intensive bus traffic.

Option AFDX

CANoe.AFDX is ideal for testing and analysis of entire AFDX networks as well as individual devices. Regardless of whether raw frames or payload contents are needed – CANoe.AFDX offers powerful analysis functions on all levels. Users quickly reach their goals and always have a clear picture of even complex network topologies.


Overview of Advantages

  • Reliable testing of data communications – from simple interactive tests to systematic automated testing
  • Automatic generation of test reports
  • Easy observation of the data traffic and comprehensive network analysis
  • Access to CAN, AFDX® and digital or analog I/O with the one and the same tool


Hardware Interfaces

CANoe .AFDX optionally utilizes the VN5610A as USB interface or TTTech's PCI/PCIe variant AFDXEnd System T.


Symbolic Display via Databases

The AFDX communication is described in ICD format. The aircraft manufacturer generally provides its suppliers with relevant description files. To ensure that this information is also usable in CANoe.AFDX, a converter is supplied that converts the ICD files into DBC files. The user adds these DBC files to a CANoe.AFDX configuration, which then enables access to symbolic information.


Message Display

The current AFDX message traffic is shown in the Trace window. If databases are available, the display is symbolic and is based on information from the converted ICD files. A Virtual Link is then no longer visualized numerically by its ID, but instead by its name. The display of columns is user configurable, and three preconfigurable column layouts are available for quick switchover. Refined search functions ensure that the user does not lose sight of key information among the large numbers of messages.

CANoe.CAN covers most use cases for ARINC 825 from simple network analysis to systematic testing of electronic units. The multibus approach lets you simultaneously operate multiple channels, different bus systems such as CAN (ARINC 825), A429 (ARINC 429), AFDX® (ARINC 664) and Ethernet.

Overview of Advantages

  • Reliable testing of the bus communications between electronic units – from simple interactive testing in design or implementation to systematic automated testing
  • Automatically generated test reports
  • Easy observation of data traffic and comprehensive network analysis
  • Time-synchronous analysis of multiple buses and optional support of Ethernet enable gateway developments and tests
  • Support of the protocol ARINC 825
  • Open interfaces and database concept offer optimal support for proprietary protocols as well

CANoe.CAN may be combined with other CANoe options such as A429, AFDX, Ethernet and CANopen.
Its intuitive operation is based on a displayed block diagram that graphically depicts the data flow from the bus over the PC interface to the various evaluation windows of the screen and to the log file. The system is parameterized in this block diagram. In addition, function blocks may be placed and configured here, uch as filter, generator or replay blocks.


The basic functions offer a multitude of usage options. They include:

  • Simulation of complete systems and remaining bus simulation via modeling
  • Tracing of the bus data traffic
  • Test entire networks and/or individual electronic units
  • User programmable with integrated C-like CAPL programming language to support simulation, analysis and testing
  • Interactive sending of messages
  • Statistics on nodes, messages, bus load and faults
  • Logging of messages for later replay or offline evaluation with versatile triggering options
  • Generation of bus disturbances
  • Creation of user-defined interfaces for controlling the simulation and tests or for displaying analysis data
  • Control of digital and analog I/O modules and measurement hardware lets you process real signal values in simulations and test environments
  • Open software interfaces such as Microsoft COM and .Net enable integration in existing system environments
