content: Hello fellow engineersI am starting project which require functional safety. From contactors to embedded software, so topic is rather big. I am now identifying applicable standards and I am looking for more knowledge, especially for good practices and guidelines for project management to ease certification process.Do you have any book recommendations? Good or bad?"Functional Safety for Embedded Systems" By Guoqi Xie, Yawen Zhang, Renfa Li, Kenli Li, Keqin Li, 2023 looks interesting for example.

content: I can't comment on that book. I was introduced to functional safety by Michael Medoff, Exida. If you go to Exida's website, click on products, and then reference materials you can look at their series of books on functional safety.Check out...Functional Safety - An IEC 61508 SIL 3 Compliant Development Process

content: Quote from: CosteC on August 11, 2023, 01:41:11 pmAre you interested in industrial or automotive?Automotive is driven by ISO26262 standard. That's basically the source of all truth as of today.

content: Industrial.Standards are on the way - it is not an issue.Challenge is more how to coordinate project to make certification as painless as possible.What are most common pitfalls? What are system design good practices?

content: First of all, you need to establish a good process.I am working in automotive safety, but the same applies to industrial.You need a proper requirement and design review processes with documented outcome.Each safety related work product has to have a confirmation review.You have to have templates or use specialized tools for each work product. If template or tool doesn't exist - you will get a finding for a process related item.At least for ISO26262, each part has a list of work products to be available (if applicable/not tailored out), so you can take that list and then see what has to be done in each work product.Begin with management related items. Planning, impact analysis, roles of safety engineers, levels of independence, preparation for audits, etc. For automotive, this would be defined in ISO26262 Part 2.

content: Good process for project is one thing yet good system design will not manifest by itself, unless there is experience in team already. And there is not much now. Hence good examples, stories and case studies are what I am looking for. Negative (fails) stories are good too, as more entertaining

content: A simple search for that IEC61508 string (also) finds a wikipedia page which mentiones some other related safety norms.https://en.wikipedia.org/wiki/IEC_61508
