Testing AUTOSAR Software Components with Ansys TPT

The software architecture described by automotive open system architecture (AUTOSAR) is a widely-used standard across the globe’s automotive software industry. Functional software is implemented in so-called AUTOSAR software components (SWC).

Testing AUTOSAR’s SWC can be done easily with Ansys TPT embedded software test tool and is easily automated. What’s more, you can test atomic SWC, compositions of multiple SWC, and do virtual engine control unit (ECU) testing with TPT software.

Automatic Generation of Test Harness and Runtime Environment

TPT software automatically generates the test harness for interfacing, which in turn serves as a test runtime environment (RTE), also generated by TPT software.

The interface with TPT software is specified using ARXML files. Multiple interfaces are supported, such as:

• Client and server ports
• Sender and receiver ports
• Per-instance memory (PIM)
• Interrunnable variables (IRV)
• Mode declaration groups
• Exclusive areas
• Calibration parameter ports

Testing SWC Works like Plug and Play

Thanks to the seamless integration of components and testing tools, testing AUTOSAR SWC with TPT software is straightforward.

The integration is done via the generated RTE. This is done either for closed systems or by way of our co-simulation platform for simulating virtual ECU.

In other words, you can test AUTOSAR SWC directly with TPT software or via plant models for complex and dynamic systems. SWC can also be tested individually, compositions thereof, or integrations of plant models of complex and dynamic systems. Software testing with TPT software is virtually plug and play testing, or, as we like to call it: run, test, drive.

Standard AUTOSAR and AUTOSAR Adaptive

 For testing according to the AUTOSAR standard, we offer special solutions for AUTOSAR SWC for the latest versions of AUTOSAR 3, AUTOSAR 4, and AUTOSAR Adaptive.
