System design and modeling, what do you use?

[kalabdel]

Hello everyone,


I've tried quite a few methods over the years starting with flow charts and finite state machine diagrams and then often a combination of the two. Last year a spent sometime on State-charts and it worked well for me though the IDE I was using, "Yakindu", and like the modeling system but not quite confident with Yakindu IDE.

I am now more inclined to invest time getting good at SysML


I have two objectives, one is to aid in the process of system development as it relates to PLC programming and the other is for documentation and customer presentation.



What do you use, works well for you and is accepted by your customers?


Thanks
Kal
