FUNCTIONAL SAFETY WITH ROOT OF SAFETY AND CHAIN OF SAFETY

Abstract:

A data verifier, comprising: a first processing circuitry, configured to perform a first safety operation, the first safety operation comprising: determining whether first sensor data representing a second processing circuitry factor satisfy a first verification criterion; and if first verification criterion is satisfied, execute a first safety measure; and if the first verification criterion is not satisfied, execute a second safety measure; a second processing circuitry, configured to perform a second safety operation, the second safety operation comprising: determining whether a first value, generated by a third processing logic from sensor data satisfy a second verification criterion; and if the second verification criterion is satisfied, execute a third safety measure; and if the second verification criterion is not satisfied, execute a fourth safety measure.
