In the context of embedded software development, the MCAL can be defined as follows:. MCAL is a software module that has direct access to all the on-chip MCU peripheral modules and external devices,which are mapped to memory. MCAL enables a very significant advantage of the layered architecture of the AUTOSAR compliant design — it makes the application and also the middleware Basic Software layer independent of the underlying hardware platform. This renders immense benefit to the product development cost and time, as there is a shift in the ECU design approach from coding to configuration.

If I have a look at the behavior of some Adc driver it is obviously not related to the AdcChannel. Therefore, I assume that the order is related to the list of references to AdcChannels in the AdcGroup. BUT: this list has no index or ID! See arxml snippet above. Or is it? Seems like in my toolchain the order is defined by the sequence how you add the AdcChannels to the AdcGroup:. In the example above? Keep in mind that the developers of the C-code often have no access or license to the Configuration-Tool-Chain.
X variants. First of all there was no relation with the channel ID and usually the macro with channel ID use to represent the configured channel. Please considered following example,. Its allocation is described in below image,.
Please see the diagram mentioned below for better understanding. Learn more. Asked 2 years, 9 months ago. Active 2 years, 7 months ago. Viewed times. Oliver Scheid Oliver Scheid 11 11 bronze badges.

Holes this will make you more clear BR, Jerry James. Thank you for citing the AR spec. But unfortunately this does not answer my actual question.

Safety-relevant software developed within the automotive domain is subject to the safety standard ISO In particular, a supplier must show that implemented safety mechanisms sufficiently address relevant failure modes. This involves complex and costly testing procedures. We introduce an early analysis approach for safety mechanisms implemented in safety-relevant software by combining model checking and model-based testing. Model checking is applied to verify the correctness of an abstract amodel of the system under test.
