ASIL: How to allocate, How to mix, What to consider

ASIL is an attribute of the safety goal derived from the hazard analysis of the functionality an system. It’s then propagated through the associated requirements and, in some cases, also modified. But what are the rules behind? Do we need to assign the same ASIL to all elements part of a safety system? What are the requirements/implications when the ASIL is assigned? And why some representations are showing an increased ASIL going through the processing chains (e.g. lowed ASIL for inputs and higher ASIL for the processing)? Join to discuss such key aspects.
