Holy shit, Rustc (via Ferrocene) being ASIL-D certified...

Holy shit, Rustc (via Ferrocene) being ASIL-D certified is a huge deal! That’s the highest level of verification for automotive applications, which enables it to be used in stuff like braking, steering, and other critical vehicle systems.

I had absolutely no idea what any of the standards were about. But now that I understand what they are, that seems huge! Amazing work by @ferrous!

Here’s an explainer of what ASIL-D certification entails:

https://en.wikipedia.org/wiki/Automotive_Safety_Integrity_Level

ASIL D
ASIL D, an abbreviation of Automotive Safety
Integrity Level D, refers to the highest
classification of initial hazard (injury risk)
defined within ISO 26262 and to that
standard's most stringent level of safety
measures to apply for avoiding an
unreasonable residual risk.!21 In particular,
ASIL D represents likely potential for
severely life-threatening or fatal injury in the
event of a malfunction and requires the
highest level of assurance that the
dependent safety goals are sufficient and
have been achieved. 2. An example of
dangerous hazard that warrants the ASIL D
level is loss of braking on all wheels.!°]

Oh even more fun: are you by any chance planning to build a chemical plant? Or perhaps a nuclear one?

Well, if you are you’ll probably want your control systems to be as reliable as possible, which is what the SIL standard is about. Apparently Ferrocene is SIL4 certified, which is the highest possible level!

Safety instrumented
system
Article Talk
In functional safety a safety instrumented
system (SIS) is an engineered set of
hardware and software controls which
provides a protection layer that shuts down a
chemical, nuclear, electrical, or mechanical
system, or part of it, if a hazardous condition
is detected.!!
Requirement
specification
An SIS performs a safety instrumented
function (SIF). The SIS is credited with a
certain measure of reliability depending on
its safety integrity level (SIL). The required
SIL is determined from a quantitative
process hazard analysis (PHA), such as a

Safety integrity level
Article Talk
XA
In functional safety, safety integrity level
(SIL) is defined as the relative level of risk-
reduction provided by a safety instrumented
function (SIF), i.e. the measurement of the
performance required of the SIF.!1]
In the functional safety standards based on
the IEC 61508 standard, four SIls are
defined, with SIL4 being the most
dependable and SIL1 the least. The
applicable SIL is determined based on a
number of quantitative factors in
combination with qualitative factors, such as
risk assessments and safety lifecycle
management. Other standards, however,
may have different SIL number definitions.[2]
