20200127872 · 2020-04-23 ·

The invention relates to an arrangement and a method performing data exchange between various integrated circuits, IC, (3,4,5,6,7) in an automotive control system wherein the data are exchanged by a bus and has the object to enable ASIL C/D system coverage and to tie various ICs (clocks, regulators, memory interfaces, sensor signal conditioners, power management ICs etc.) This is solved the data are exchanged by a bus being ASIL C/D compliant and forming a common protocol to exchange information among the integrated circuits (3,4,5,6,7). The method is solved by functions implemented within the bus as setting the frequency of operation; arbitrating roles of the integrated circuits as master or slave device; checking integrity of exchanged data; frame repetition; detecting bus stuck- at failure modes; filtering or denouncing failures and warnings from peripheral devices; detecting remote out of specification local clock; and monitoring and predicting system reliability and profiling maintenance events.
