Goals with OSCAR

Guarantee that the electronic architecture design ensures the requirements :

Functional Dysfunctional (failure injection)

First evaluation of the impact on the networks and on the ECU

Advantages with OSCAR

Allows common works for all teams with one modelIncremental design from system level to implementationResults used in components specificationsContinuous test and verificationDetection of errors early in the development

To get higher performances, we need to define rules on the Simulink model
