Available soon: I2C fault injection

Solectrix is currently working on a new proFRAME feature that significantly extends the testability of cameras and ECUs. The feature is called I2C Fault Injection and, as the name suggests, offers the user the possibility to manipulate the I2C communication between an ECU and a camera by injecting faults. For this purpose, the proFRAME is operated in TAP mode as a so-called “man in the middle” between an ECU and one or more cameras.

I2C Fault Injection enables the implementation of various test scenarios. For example, the proFRAME can be used to generate bit errors – in reality possibly caused by faults on the I2C transmission path. Alternatively, return values from a sensor in response to a register read command from an ECU can also be changed. An example of this is the targeted setting of error bits of a camera sensor (e.g. “temperature too high”) in order to validate the ECU’s reaction to such an event.

First implementations of this feature are already available, and the proFRAME development team is currently working on optimizing the feature in terms of performance (latency) and user-friendliness.
