SM CODE COMP_SM_1
Description 1oo2 scheme for comparator
Ownership End user
Detailed implementation
This safety mechanism is implemented using the two internal comparators to take the same
decision. It requires that the comparator voting is handled accordingly.
Error reporting Depends on implementation
Fault detection time Depends on implementation
Addressed fault model Permanent/transient
Dependency on Device configuration None
Initialization Depends on implementation
Periodicity On demand
Test for the diagnostic Not applicable
Multiple-fault protection CPU_SM_0: Periodic core self-test software
Recommendations and known limitations This method is not compatible with window comparator feature.
Table 83. COMP_SM_2
SM CODE COMP_SM_2
Description Plausibility check on inputs
Ownership End user
Detailed implementation
This method is used to redundantly acquire on dedicated ADC channels the analog inputs
that are subjected to comparator function, and to periodically check the coherence of the
comparator output on the measured values.
Error reporting Depends on implementation
Fault detection time Depends on implementation
Addressed fault model Permanent
Dependency on Device configuration None
Initialization Depends on implementation
Periodicity Periodic
Test for the diagnostic Not applicable
