FAQs Regarding ISO 26262 Compliant ECU Testing Services

    Ans. Primarily, we partner with the customers based on the “Time and Material” business model. The billing is charged based on the actual man hours and cost of equipment (3rd party tools etc.) for the project.

    However, once the project and relationship mature and we gain deeper understanding of the code complexities, tool requirements and future changes, the business model can be changed to “fixed price model”.

    Ans. The following is the indicative list of the testing tools that we have worked with, during ISO 26262 testing projects are as follows:

    • CANTATA for Unit and Integration Testing
    • MX-Suite for unit testing and software verification of embedded system
    • RTRT for Unit Testing
    • Polyspace to check coding guidelines and static verification process

    Our hands-on experience of working on these tools include projects on different ECUs. We can share more details once we sign the NDA.

    Ans. The security and integrity of the code is our number one priority, as per the NDA signed with our customers.

    We adhere to the GDPR and ISO 27001 guidelines for the code safety and integrity.

    Secure FTP is also always made available, to ensure that code is transferred in a secure environment.

    Ans. When you partner with Embitel, for ISO 26262 compliant testing services, you collaborate with an expert core team of:

    • Functional Safety Consultants
    • Project Managers
    • Testing Engineers.

    Here is the team hierarchy that is most commonly followed in the ISO 26262 Testing Projects:

    Functional Safety Manager: Ensures that the ISO 26262 testing guidelines are followed in letter and spirit, during the testing processes. For all the technical discussions, the Functional Safety Manager will be your SPOC.

    Project Manager: Manages the entire project execution and coordinate between the team and the customers.

    Testing Engineers: Collaborate for Unit Testing, Integration Testing and Validation activities

    Ans. We do have an onsite/offshore business model, in which we provide resources to our customers for testing projects.

    Our engineers travel to the customer’s location to perform software testing. This is usually opted when the customers have certain tools or environments specific to the project.

    Alternatively, the customers can also set up an off-shore development center (ODC), where they can send the work-products for testing, under a secure environment.

    We will perform the tests and share the report within a stipulated span of time. We will ensure that a secure communication infrastructure is created to protect the integrity of the code.

    Ans. Following reports will be provided, as deliverables of ISO 26262 Testing Project:

    • Unit Test Reports, Integration Testing Reports, etc.
    • Tool reports from tools like CANTATA, MX-Suite etc.

    If the customers require the reports in any specific test template, we can support for the same.

    Ans. We share weekly or monthly Timesheets with the customers to keep them apprised of the developments in the project. The timesheet covers the completed processes, pending activities, health of the project etc.

    The project managers also have regular calls with the customers to give the heads-up on the project. This is how the communication channel is maintained and project is supervised.

Knowledge Bytes
  What is ISO 26262 testing of automotive ECU?
    The dimension of ISO 26262 mandated functional safety is added to the testing process when the final automotive solution must be ASIL compliant. ISO 26262 standard specifies certain guidelines in parts 6.9, 6.10, and 6.11 that must be followed during the unit testing, integration testing and static verification process of automotive ECUs.

    The ISO 26262 standard emphasizes on the inputs and output of the testing process but does not recommend any specific way of performing the tests. However, it does recommend certain certified tools like CANTATA for the purpose.

  What is CANTATA tool? How does it help in ISO 26262 ECU Testing Projects
    CANTATA is a unit and integration testing tool that enables the developers to verify the code against standards such as ISO 26262.

    CANTATA is one of the ISO 26262 certified testing tool that helps meet testing requirements laid down by ISO 26262 standard. It is the recommended ECU testing tool in scenarios where the automotive product is aiming for Automotive Safety and Integrity Level (ASIL B, ASIL C or ASIL D) certification.

    CANTATA automates the following ECU testing activities to accelerate ISO 26262 compliance process:

    • Generation of Test Frameworks
    • Test case generation
    • Execution of test cases
    • Test report generation
  Which are the tools other than CANTATA which aid the developers in ISO 26262 Compliant ECU testing?
    During automotive software development, different kinds of tests and verifications are carried out viz, unit testing, integration testing, static analysis, dynamic analysis, design verification etc.

    There are certain specialized tools for all these testing and verification activities. Following are some widely used ECU testing tools:

    1. PoySpace- The tool serves dual purpose. First, it helps in static code analysis in order to detect any run-time error in C code. Second, it checks the source code to ensure the adherence to coding practices and standards such as MISRA.
    2. RTRT- RTRT is a multi-purpose automation tool for code testing. In automotive ECU testing projects, it is mostly used for unit testing, coverage analysis and system testing. It creates test scripts, test cases and rest reports. It also supports regression testing.
    3. LDRA- It provides a complete suit to automate the ISO 26262 compliant testing and verification processes.
      LDRA helps meet these software quality and test requirements:

      • Requirement Traceability
      • AUTOSAR and MISRA C Compliance
      • Statement, Branch and MC/DC coverage
      • Model Based Development
      • Mx-Suite- Mx-Suite is a complete tool for automotive ECU Testing, especially when the software has been developed using the MBD approach. With an intuitive GUI, it is easy to create tests. Moreover, test cases can be reused in all phases of testing, i.e. Model-in-loop (MIL), Software-in-loop (SIL) and Hardware-in-loop (HIL).
