But if you are a Safety Engineer who never worked on SW but are asked to perform SW Safety Activities, then the Part-6 is surely “Tricky Dricky”!! This article is targeted towards Safety Engineers who are unfamiliar with SW. We have taken a specific set of requirements from Clause 5 of Part 6 and attempted to simplify it. This is Part 1 of Clause 5, and we will do another Part-2 for the same clause.

ASIL Operating Systems - Which is your pick?

If you are working in the software of a safety critical product, you are most probably using an ASIL 'certified' Operating system in it.  The market is flooded with various ASIL-certified Operation Systems (OSs) from various Tier 2s. On top of it, several Tier 1s and OEMs themselves are developing their own OS in ASIL compliance. This blog summarizes the ASIL-certified OSs that are available in the market, what features they provide and what do they promise for its users. Disclaimer : We have analyzed only the public literature available for the various OSs and written this article based on what we learnt from them. We do not have working experience in most of these OSs. Hence, we could have missed describing some of the features that are available in these OSs simply because it was not stated in their public literature. We have structured the content of this article as follows: What are the broad expectations of an Operating System from a Functional Safety perspective? What ar
