Highlight Features ECU-TEST 2022.2

Linux support

With the release of the new ECU-TEST version 2022.2, test cases can now also be executed at scale in Linux-based cloud systems. For ECU-TEST users who previously worked under Windows, it is thus quite easy to switch to an SiL test environment in the cloud.

The delivery contents of the ECU-TEST Runner include a DEB(debian) package, the user help and setting instructions. The instruction will support the user in setting a docker container which can then execute the runner. At this time the Ubuntu version 20.04. LTS is supported. The Linux version of ECU-TEST will not include a graphical user interface.

For more details about ECU-TEST under Linux have a look in our video.

Library workspace

In ECU-TEST there is a new library function – the library workspace. The packages, project generators and user Python modules (UserPyModules) of a workspace can be outsourced to this.

This is practical because the content created in the library workspaces can then be integrated into packages and projects in other workspaces as usual and reused there.

In ECU-TEST, the elements of the library workspaces are clearly distinguished from those of the main workspace by their blue color scheme.

A workspace can use any number of library workspaces. The integration of such libraries into another workspace is done by specifying the path in ECU-TEST settings. The creation of a library workspace is also done via the Manifest page in the Settings dialog.

ECU-TEST 2022.2


In modern E/E architectures, increasing security measures are being adopted to prevent known attack patterns on vehicle communication. One measure consists of cryptographic protection of parts or all of the onboard network communication.

In addition to IPsec and TLS, implementation of the MACsec protocol in the onboard network can also serve this purpose.

ECU-TEST now also allows for securing of cryptographically protected Ethernet networks. For this purpose, the built-in network solution offers establishment of and communication over MACsec-protected channels.

Session keys are negotiated using the MACsec Key Agreement (MKA) in conjunction with a static (pre-shared) Connectivity Association Key (CAK).

Currently, only integrity protection is supported. Encryption is not yet part of the range of functions.

ECU-TEST 2022.2

Time synchronization via CAN and FlexRay with Vector hardware

With ECU-TEST it is now possible to specify a precise time on a bus system according to the following AUTOSAR protocol:

  • Time Synchronization over CAN/FlexRay or IEEE 802.1AS

In addition to supporting the timing slave, ECU-TEST assumes the role of timing master.

Activation takes place on a manipulation port via the job:

  • StartTimeSyncMaster

To ensure accuracy during implementation, hardware timestamps from the Vector measurement hardware are used. If there is a need for additional measurement hardware support, please feel free to contact us.

Efficient filtering of very high Ethernet data rates for multiple PLP data frames

In previous versions of ECU-TEST, improvements were implemented for the evaluation of passively received SOME/IP messages regarding performance. The efficient filtering of very high Ethernet data rates contributed to this.

These filtering mechanisms now also take effect in connection with CMP/PLP data streams. The BPF generator supports filtering of up to four PLP data frames in a PLP packet. The following job is available for this purpose:

  • LearnBPFilter


Value-added services, such as querying the vehicle's charging status, are already possible away from the vehicle via app and web interfaces.

In order to be able to test vehicle communication with the backend, as well as the functionality of actions via web interface, ECU-TEST now offers a connection to Selenium – a framework that simulates user interactions with the web browser.

For this connection, different jobs are available in ECU-TEST, which can be used to check the content of the web pages for different criteria (image, text).

The prerequisite is a web driver for the browser in question, e.g.:

  • Geckodriver.exe – Firefox
  • Chromedriver.exe – Google Chrome

In the testbench configuration, paths are set to both the installed web browser and the web driver.

Highlight Features in ECU-TEST and TRACE-CHECK 2022.2

Updating the GUI library

ECU-TEST 2022.2 now uses wxPython 4.1.2 as framework for the graphical user interface.

This change was technically necessary to be able to guarantee a high functionality both now and in future. Visually, only details have changed, such as the display of the accordion menu in the editor or the generally flatter and more modern view of the user interface. Nothing has changed in the menu navigation itself.

If you encounter problems with custom GUI elements, please contact our Support.

ECU-TEST 2022.2

Knowledge base for even more direct support

With our Knowledge Base, we have created a platform where users can find solutions to frequently-asked questions about the use of our tools. Its integration into our Support Center means helpful articles are already displayed when a new request is formulated – in some cases, this means that a support ticket is no longer necessary.

In ECU-TEST, the Knowledge Base can be reached via the Help menu with one click.

ECU-TEST 2022.2

Highlight Features TRACE-CHECK 2022.2

DTLS support in PCAP trace analysis of service-based communication

Increased networking of onboard communication with backend systems, as well as new legal regulations, make it necessary to protect communication from cyber attacks.

The DTLS (Datagram Transport Layer Security) security protocol enables authentication and even encryption of vehicle communications, so that they are protected from tampering and interception. DTLS is based on the functionality of TLS, but uses the unsecured transport protocol UDP instead of TCP.


The current version of ECU-TEST supports the analysis of service-based communication with DTLS 1.2 from PCAP traces. In particular, key files exported with Wireshark can be reused. If you are interested in extending this feature (e.g. TLS support) please contact our support service.

Abort of trace analysis in the case of synchronization errors

Successful synchronization of multiple traces from diverse sources can be an essential prerequisite for their processing. If it is not possible to establish synchronization with the required accuracy, time-consuming post-processing of the recordings (trace merging and trace analysis) does not make sense either.

In the new version of ECU-TEST, therefore, the option to Continue on error has been added, in order to cancel post-processing in the event of an error, and free up valuable resources.


IP reassembling support for PCAP trace analysis

Especially when transmitting large amounts of data, it may not fit into a single IP data packet. In this case, the data is fragmented into several packets. The current version of ECU-TEST is able to reassemble these packet fragments from PCAP traces and analyze them as if they had been transmitted as a whole.

Apache Parquet Traces support for trace analysis

Apache Parquet is an open-source column-oriented recording format for high-performance analysis of large data sets. With ECU-TEST, it is now possible to analyze Parquet files (.parquet or .pqt).
