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
- Tessy tool for automation of unit testing actvities as per ISO 26262 standard
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.

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:
- 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.
- 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.
- Tessy is a Test System designed for automated unit and integration testing. Being an ISO 26262 qualified tool, Tessy is ideal for the development of automotive solutions with safety-critical requirements. It automates the entire Unit Testing cycle and also performs the regression testing.
- 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
