[aadl]: Wiring Analysis Software

[Hall, Brendan (MN65)]

Alex,

You are correct.

Mentor’s System Vision is  a great tool to look at. Also,   remember that this  is built on top of the open VHDL-AMS standard. Hence there are many tools here (the joys of well developed standards). That said  I am not certain of open source simulators, although I believe there are freely available educational offerings  from Vendors.
This is a great resource for the background technology  https://www.elsevier.com/books/the-system-designers-guide-to-vhdl-ams/ashenden/978-1-55860-749-1

On the Mentor site there are some great videos, that show the impact of wire and cabling
Check out the LVDT Sensor Modeling and Signal Conditioning Design

Also check out the CAN examples on the site

We are just starting to look out how we can link these models to the architectural models and potentially integrate  error annotations and cross model parameters.
Establishing the system context for the analysis and mapping the  key parameter influences is a interesting problem. The AVSI-SAVI  project is starting to look at this next level of cross model integration.

There are some interesting approaches linking the VHDL_AMS to SysML that may also be of interest.

In the longer term I’d like to see a similar relationship with the AADL hybrid annex. But we need some use cases to better understand the potential and needs  here. Linking to the higher level system separation and safety constraints may be a sweet spot.

Happy Monday

That is a very interesting and pertinent thing that is much needed in aircraft since wiring bundles add weight to aircraft. There is need to optimize the routing to reduce the length but also to provide understanding of the accessibility to maintenance (i.e., where to put connecters, taughtness, etc). Also, being able to do virtual analysis of possible chaffing, current carrying capacity, weight analysis, zonal safety analysis of the routing, etc. All of these different types of analyses would have to be currently handled sith different tools to account for routing, weight, safety analysis. I think Mentor Graphics has tools that are available but I am not aware of open source tools to do these all. Would have to do more research, but great question!

Hi
I want simulate and analyze the wiring of aircraft. do you know about any software that i can simulate, design and analysis of wiring and finally optimize the wiring design?
thank you for your attention
Mohsen
