1 OVERVIEW 

RTE is an implementation of the Autosar virtual function bus VFB interface between the application layer and the basic software layer in the Autosar software architecture, providing Infrastructure services for communication between application software ASW software and facilitating access to basic software BSW components including OS.

RTE testing includes testing of interfaces between COM, DIAG, NVM and SWC. However, judging from the current market situation, RTE testing tools and methods are scarce. The reason is that the market scale dedicated to RTE testing is small and most suppliers are reluctant to develop RTE testing tools, resulting in extremely limited selection of testing tools and expensive. Moreover, across the industry, most tools related to RTE testing are based on configuration tools, debuggers, and bus tools for manual white-box testing. For thousands of RTE interfaces, the test volume is huge and consumes a lot of human resources.

In response to the problems described above, ZC can provide a complete set of RTE testing solutions to solve customers 'worries.

2 TEST POINT

The RTE test mainly targets the Read and Write interfaces between SWC and BSW, and different test strategies are formulated according to different interfaces. Including but not limited to:

Ø  Interface between SWC and SWC

Ø  Interface between SWC and COM

Ø  Interface between SWC and DIAG

Ø Interface between SWC and NVM

Ø Interface between SWC and SPI

4 TEST EQUIPMENT DESCRIPTION

 4.1 hardware requirement

4.2 Test environment software

Vector CANoe series tools, version Canoe12.0 and above

5  Example of ADAS RTE test steps

5.1 Simulate real scenes, such as identifying lane lines and obtaining lane line data

5.2 Receive data through debugger observation

5.3 Compare the original signal data file to determine whether the data obtained by the SPI-sensing camera is consistent with the debugger data.

5.4 Test whether the interface between SWC and SPI is correct.

Use the debugger to read the signal data in the structure in RTE_Write to calculate the real physical value.

Through the correspondence between signal values and variables in the structure, find the data of the structure read under the Rte_Read interface, and find that it is consistent with the original calculation, if the test is correct. 

5.5 test report

According to the AUTOSAR_SWS_RTE specification and the test requirements of the customer's RTE interface, test cases are designed through equivalence classes, boundary values and other methods, and test reports are completed to ensure two-way traceability and consistency.
