Hi Guys,

I do not know if this will be of interest, nor of use to us, but it is a very interesting, and academically grounded, paper on some of the connections among systems architecture, requirements, and safety critical systems.

IMHO it is light on systems architecture and heavy on requirements traceability and provability, but it is valuable none-the-less.  There may be something we can leverage in our RASDS++ update process.

Cheers, Peter

I'm new to this forum and I've seen this group is much helpful.

I'm pretty sure SysML is widely used for developing architectures/models for FuSa. I've below questions if someone could clarify, that would be great.

1) Has anyone in this forum used Rhapsody for developing System Architecture for FuSa? 2) What are the key points that one should be aware of while developing the model for FuSa?
3) Have you used stereotype to specify the ASIL levels for each blocks?
4) Is there a good example or reference available?
5) My scope is to develop a SysML Model (BDD, IBD) for an FuSa product and use Medini for Safety Analyses.

Thanks in advance,
