Line control method to decide transmission reception là gì năm 2024

The analysis aims to evaluate the information exchanged between ECUs and software functions. Information exchange can be implemented in the virtual space between software functions, using networking technology (bus systems, networks), or hardware connections (digital/analog).

The level of detail ranges from physical values (current, voltage, etc.) and digitized binary information on protocol packets all the way to signals represented by symbols that can be displayed in various CANoe analysis windows.

Diagnostics with CANoe

Variant Coding window: This diagnostics window is used to read, write and compare variant coding data of an ECU. Security aspects from possibly configured security sources are taken into account.

In CANoe you can test and simulate ECUs diagnostically. In this process, interventions can be made at all essential communication layers - e.g. to deliberately provoke errors. CANoe supports all relevant automotive networks and transport protocols. You can perform diagnostic tests automatically, semi-automatically as well as interactively. For interactive tests, a diagnostic window is available for all important use cases (e.g. reading fault memory, variant coding, OBD-II).

Simulation of Functions and Communication Processes

You can test and analyze a System Under Tests (SUT) with a CANoe simulation. By transferring real components to a simulation under laboratory conditions, the SUT is operated under defined, controlled and, above all, reproducible situations. This makes it possible to analyze limit and exceptional situations without risk. All development phases are supported with this residual bus simulation.

The SUT can be hardware as well as software.

Stimulation with CANoe

During stimulation, events are applied to a System Under Test (SUT) to produce a desired response. These stimuli can be of the character of a planned control or of a scheduled system disturbance for further investigation. The goals of a stimulus are:

• Controlled, reproducible excitation of your SUT
• Various test scenarios for your analyses
• Determine optimal control parameters

Testing of ECUs and Entire Networks with CANoe

CANoe represents the state-of-the-art test environment. It is the ideal testing tool as well for the entire system as for efficient ECU testing. CANoe supports you with impressive performance on:

• ECU tests
• Module tests
• Integration tests
• Conformance tests
• Regression tests
• Testing of ECU prototypes

For your convenience the Test Feature Set (TFS) is integrated in CANoe. It performs both application-specific tests and standardized conformance tests.

On increased real-time requirements, you may also operate CANoe as a HIL (Hardware-in-the-Loop) system.

In the CANoe RT (Real Time) mode, real-time relevant simulation and test functions are executed on a dedicated computer, i.e. separate from the graphic user interface. This offers you an easy way to increase the overall system performance if necessary. Additionally it results in shorter latency times and more precise timers.

Application examples

CANoe’s many open interfaces make it easy to adapt it in your testing environment:

• Integrating hardware for stimulation, measurement and injecting errors: VT System, digital and analog I/Os, automated measuring devices, controllable power supplies
• Interfacing simulation and test models: MATLAB/Simulink models
• Controlling test systems from third parties: via program calls, script calls
• Integration in higher-level test controllers: via the CANoe COM server, e.g. from Python or .NET
• Linking to external software tools: e.g. to DOORS for traceability requirements

Monitoring and Debugging of AUTOSAR ECUs with CANoe

Workflow of CANoe .AMD/XCP

The CANoe Option AMD/XCP (AUTOSAR Monitoring and Debugging) supports access to internal parameters in the ECU. It gives you extensive test options and shortens your debug times substantially.

Especially with complex ECUs or distributed functions, a pure blackbox test is no longer adequate. Access to internal information in ECUs opens up new and comprehensive test options for your application or ECU stack. AUTOSAR ECUs, in particular, offer defined interfaces for measuring and stimulating test parameters due to their structured layout consisting of basic software (BSW), a runtime environment (RTE) and software components (SWCs).

Highlights:

• Easy access to internal ECU parameters over XCP/CCP
• Extensive measurement of the MICROSAR stack (supports all monitoring features, including generic measurement)
• Update of A2L files with new addresses from the linker-map files (via the included ASAP2 Updater)

Application Areas:

• Extended test options through access to ECU internal values
• Analyzing and automated testing of ECU internal values, bus signals and I/O signals
• Analysis of distributed functions with parallel access to several ECUs
• Debugging in BSW and SWCs
• Automatic configuration via ASAM A2L file

CANoe as Open Environment for Functional Testing in Embedded Systems

In a heterogeneous tool environment – with highly specialized tools for the respective subareas of a complex simulation and/or test setup – it is necessary to integrate the individual tools as well as possible into a network. Interfaces and tool coupling options for special tasks are helpful here. CANoe supports you in a variety of ways:

Communication Concepts: Current Development

"Service-orientation in E/E designs" (26 min.). 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

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.

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.

CANoe Communication Concept - 3 Top FAQs

Q: Does the communication setup replace the simulation setup? A: Yes, the communication setup was specifically designed for service-oriented architectures for which the network oriented representation in the simulation setup is not suitable. Q: Do I have to change my existing CANoe configurations? A: No, existing CANoe configurations can continue to be used unchanged. However, in the future more and more OEM extensions will be converted to the communication concept. Q: Is the communication concept only suitable for AUTOSAR Adaptive? A: No, the communication concept covers all types of communication. This ranges from cyclic CAN messages to MQTT for IoT applications.

Importance of the Communication Setup Window

This article explains the concept of a universal communication system which, in addition to purely signal-based communication, masters the handling of Service-Oriented Architectures and enables the equal treatment of any desired forms of communication during testing.

Testing of Security-Protected ECUs and Networks

The principle of the Security Manager - with and without access to OEM-specific backends

Security mechanisms in the ECU secure the vehicle and its functions against manipulation and unauthorized access. However, for testing and diagnostic purposes, it must be possible for an authorized individual to participate in vehicle communication during development and later operation.

With the Security Manager, Vector offers a uniform solution that is used identically for many Vector tools. In addition to CANoe also , CANape, vFlash, Indigo and use the Security Manager.

Technical Article "A Look Behind the Scenes"

Blackbox tests are typically conducted in the framework of ECU development or in analyzing faulty ECU behavior. This involves connecting an ECU‘s inputs and outputs to a test system for stimulation and measurement. Although this method lets the test engineer perform extensive analysis, certain tests require looking directly into the ECU. This is the only way to obtain meaningful test results or reduce testing effort. (Open Technical Article)

CANoe Options for Aerospace

Option A429

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 or VN5650 as USB interface.

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.

Option CAN | A825

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.

Functions

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
