Introduction to functional safety at Freescale and understanding the generic fundamentals. This session will discuss the key content of the Safety Manual and Dynamic FMEDA, plus how they are used by the Automotive and Industrial customer.
Just one question related to MCUs FMEDA and more precisely the PMHF total rate. I could not understand exactly which is its value. For instance on slide 34 there is the sum of SPF and RF resulting in 2,18 e-10, so way below the ASIL D threshlod and also fulfilling general commitment of MCUs within the total budget of PMHF rate (1%). But right below that there is another "total lamba ISO 26262" calculated which is three orders of magnitude bigger (10e-7 compared to 10e-10), furthermore on slides 17 and 18 there are some mentions about total MCU raw FIT rate (about 10e-6) and that they should relate somehow to ASIL B (actually the verbatim statement is : The objective is to make SW execution safe to achieve ASIL B) and then an arrow in the ASIL grading figure, pointing from MCU raw to ASIL B ..
What's the connection between all that? How much is at the end the total FIT rate for the entire MCU (PMHF metric)?
