How We Performed Ethernet Protocol Testing in ADAS Unit for a leading Automotive Tier1/OEM

By June 24, 2021August 1st, 2024No Comments

Streamlined communication in the ADAS system for a top-tier automotive OEM through protocol automation and code optimization. This enables the swift delivery of highly efficient ADAS systems with enhanced safety standards.

Ethernet Protocol
Automation Confirmation

97% of time span reduced while comparing to manual test confirmation
Cost of testing reduced by more than 80%

Business Goals

Accelerate Development, Verification, Validation, and Delivery of Design Prototypes.

  • Assess feasibility for test automation.
  • Improve communication, service discovery, and overall functionality within the automotive system.
  • Align OEM software test items with Ethernet protocol standard items.
  • Implement ‘Profile 4’ safety mechanism for End-to-End (E2E) in CAPL as per AUTOSAR standard.
  • Address Complexity in Client/Server Ethernet concept for a single CAPL Program.

Solution

Modernized workflow with a one-click tool, automating model design and testing for enhanced efficiency.

  • Employed advanced in-house CAPL functions within vTESTstudio, enabling seamless auto code implementation and conducting comprehensive feasibility assessments.
  • Leveraging the SOME/IP SD concept, we enhanced communication, service discovery, and system functionality remarkably.
  • Thoroughly investigated AUTOSAR standards and client specifications, ensuring precision in software implementation strategies.
  • Strategically divided complex modules, enabling targeted creation of simplified auto code creation.
  • Harnessing the power of PYTHON scripting, we expedited testing processes by creating an Ethernet communication matrix.

Outcomes

  • Enabled universal usage of the generic auto code for all Ethernet protocol tests.
  • Incorporated safety standards (ASIL) into the auto code, meeting client software delivery requirements.
  • Diagnosed and improved Ethernet interface software for efficient frame data transfer.
  • Optimized auto code facilitated the selection of suitable Ethernet network hardware modules like VT6306 and VN5610A, ensuring proper Ethernet communication.
