I believe the HighTec LLVM based compiler is also ASIL-D certified.

ISO 26262 certified for Tricore
released, but not certified for arm

I think Miri calls itself an UB detection tool so maybe that should slot in here? Or elsewhere?

| | Static Analysis Tools | DAL-C | | - make sure coding guidelines specify some rules, probably similar to Polyspace, <br> - an assessment about what the rust compiler covers is necessary <br> - for DO-178 such tools support the *source code conformity* objective | | ||
| | Unambiguous Graphical Representation | ASIL-B | UML like too, but for Rust, AUTOSAR suggests - [Explanation of ARA Applications in Rust](https://www.autosar.org/fileadmin/standards/R23-11/AP/AUTOSAR_AP_EXP_ARARustApplications.pdf) | | ||

Verus is in beta but a formal verification tool that might get thrown in here.

Would property based testing like proptest fit in here?

Was notified of I know we had the discussion last time that the Venn diagram of "safety-critical standards" and "formal methods" tend to have little to no overlap, but thought I'd mention it as it came up here. |

This pull request adds a list of requirements and existing tools of safety critical certification. This reflects the results of the meetings of the tooling subcommittee.
@af-airbus please take a look at the DAL related entries, some of the lines in the table do not have a DAL minimum requirements
@jgust @Bgenis @pellico and @jmqd please take a look at the ASIL minimum ASIL items, some of the lines of the table arte missing ASIL
