Test & Verify

Testing, verification, and validation

Techteal can support you in all phases of the development process, for you to learn, implement and test/verify various ideas and solutions, focusing on Automotive Ethernet, Time-Sensitive Networking, and V2X/OTA. You may use our expertise or buy off-the-shelf products to test, verify or validate on your own.

ECU simulation

Ambition is to simulate and recreate the real world out there - under real-world conditions

Ethernet as a well-established technology is still challenging because of the complexity of testing. Based on the architecture and multiple protocols involved (7-layers of the OSI model) – engineers are challenged with different test methodologies:

  • Physical layer testing

  • Protocol conformance testing

  • Device- and network performance testing.

In the testing process, you need one or several tools which simulate the behavior of an application, function, device, or network, with the ability to investigate the behavior of your device/system/implementation under test under real-world conditions. This process is different from traditional test methodologies. The integration of multiple Ethernet devices and backbone components like switches or gateways into a network will always have different behavior than single components.

​Just simulating other devices on the application layer only validates the functional layer, but not the network layer. Simulation of best- and worst-case scenarios on the network layer is essential for full validation. Adding a network simulation that incorporates the simulation of switch functionalities, protocol behaviors (like Time-Sensitive Networking), or even network behaviors like delay, jitter, and packet loss can add to your validation.

Standard testing

New technologies often require new strategies for their analysis and validation. Techteal can assist you in developing efficient, flexible, and reliable test strategies.

This includes in particular the development of standard tests for technologies such as Automotive Ethernet and its IVN protocols but also V2X protocols. We recommend the usage of RFCs, OPEN Alliance TCs, and other standards for benchmarking and interoperability testing. For functional testing, we propose using the extensive knowledge from previous projects with the simulation of real-world traffic. Techteal can help you create test systems, test specifications, and test cases, set test priorities, and develop customized test systems, using the best-suited components from our key partners.

Key areas:

  • Functionality testing

    • Simply, the system must consistently behave as the user expects and deliver
      the performance promised in any reasonable scenario

  • Interoperability testing

    • In the automotive industry, the need to interact well with other third parties is a new challenge. Failure to confirm interoperability will negatively impact safety, customer experience, and public trust in a brand

  • Safety testing

    • Whatever happens, the system must not place the driver in danger. This
      applies both to reliability (that it works) and latency (that it works quickly

  • Quality of Service testing

    • QoS is well established in telecom and computer networking, as
      a measure of the performance experienced by users. As vehicles
      become increasingly connected, it is essential to check in-vehicle networks
      deliver as they should

  • Type approval testing

    • As standards become established for connectivity, they will become
      integral to vehicle type approval specifications and other regulations, which may vary between territories.

Test automation

Developing scalable tests has never been easier. By for instance, using a product called TTworkbench from Spirent you can choose from a variety of already existing plugins and test solutions, or start your test automation project from scratch.

Comprehensive test automation ensures maximum reliability and reproducibility and automated test processes save time and are therefore particularly cost-efficient.

Key areas:

  • As an example, Spirent's TTworkbench is a full-featured integrated test development and execution environment (IDE) for any kind of test automation project

  • With a complete range of RF and wireless testing solutions, Techteal and Spirent can help you design and implement sophisticated V2X communications services

  • There are different ways of integrating a test suite into your management environment. Techteal together with its key partners offers ready-to-use integration plugins, open integration and development interfaces (in case your platform is not being supported yet), or a full integration service.

Test scenario example

A PC/Laptop is the Tester which require full control over everything. It has to see everything and it has to manage everything in the complete scenario.

A typical set-up:

  1. Connect Tester to (send), i.e. Stimulation

  2. Connect Tester to (listen all). i.e. Logging

  3. Connect Tester to (restart). i.e. Diagnose

  4. Connect Tester to (modify system settings.), i.e. MediaGateway configuration

Test scenario MediaGateway

Test scenario using Technica's ANDi and MediaGateway to diagnose and log all data to and from a DUT (Device Under Test)

  • Time-Sensitive Networking (TSN)

    • Verifying mission-critical Ethernet network performance: New automotive network implementations have to meet the challenges of latency, QoS, conformance, availability, and synchronization. TSN standards enable these problems to be solved. If implemented correctly, the TSN extension of Ethernet promises the performance and reliability that time- and safety-critical automotive applications require.
