Abstract:
The rapidly growing amount of software in embedded real-time applications such as driver assistance functions in cars leads to an increasing workload in the field of software testing. An important issue is thereby the timing behavior of the software running on the target hardware. For testing this issue, real-time capable Hardware-in-the-Loop platforms are needed. These testing platforms are mostly custom-made, proprietary and in consequence expensive. Moreover, many software developers usually have to share few instances. This paper shows an approach for a real-time capable Hardware-in-the-Loop platform based on a common off-the-shelf PC running a non-real-time operating system. Thereby, the simulation software runs on the developer's desktop computer while an extended I/O interface ensures the real-time communication with the System Under Test even for complex timing requirements as shown in an example.
