In-house Testing of Highly Hardware-dependent Software 2006-01-1556

In modern automotive systems, the complexity is growing by incorporating highly sophisticated microcontrollers running with more than 100MHz and consisting of more than 2500 registers. Software complexity is also growing in a similar, if not higher, rate.

As semiconductor suppliers are also expected by their customers to include a hardware-dependent software layer in their products, testing must now include not only the hardware product but the delivery bundle of hardware and software modules.

Testing this hardware-dependent software is complicated by the big amount of possible hardware-dependent configurations for this software layer which also extensively change the hardware test bench used in verification. The challenge of configuration complexity is solved by extensive use of test automation for both software generation, test bench configuration and test case runs. Additionally, in order to test the full delivery, all software modules have to be configured and tested together in a system-like test.

This paper will discuss the Infineon approach in testing the microcontroller abstraction layer (MCAL) of the AUTOSAR implementation on 32-bit platforms.
