But what are you certifying against? I would say that certification should be that you have demonstrated that your systems are immune to radiation hazards to some level; that you have mitigated metstability failures to some small level; and so on... but if we don't know what those possible failure modes are, and/or if we don't analyze them, we can't define the standard in the first place.
If the auto industry wants to take the lead, here, they could simply start doing the analysis and then they can write the standards! Yes, they can! And I'd be happy with that if they prove they have done the analysis and that they understand the results and that the standards they set forth are reasonable. Oh, and there needs to be a public review of all of this.
