Hi Miro, regarding your question the only comparable solution I know is from a relativly small consulting company located in Munich. They are doing many things that Quantum Leaps does with their framework called eTrice (https://www.protos.de/produkte/etrice-modellierung-in-eclipse/). They model state machines, generate code and also use traces to verify behaviour on real hardware. They worked as project partner and developed theit mini HIL project based on thos thechnique. I also tried to do something simillar on another project, but it never got beyond the demo stage as customer acceptance was not really present (meaning the time to setup the testframework was considered to high, compared to the benefits they saw) sadly.
But I think I will get your demo, play a little bit an give another try on my next project!

Thanks a lot for the pointer. It seems that I haven't yet heard of eTrice and the PROTOS company. They introduce eTrice as "Modeling of embedded systems with ROOM". QP also started as a "minimal ROOM virtual machine". Very interesting!

Correctly they started by using ROOM for 2 reasons

  • technical background of founders
  • ROOM is much easier to start from than current UML2 which brings much more features and confusion
    As far as I remember they are also integrated somehow in the Eclipse framework.

Yes, I'm just looking at eTrice on the Eclipse Foundation website ( https://www.eclipse.org/etrice).

12:41:05	 From  Enrico : Miro is legend.
12:41:18	 From  Al Anway : great presentation, Miro!
12:41:21	 From  Quantum Leaps : Thanks a lot :-)
12:47:02	 From  Tim Michals : Can CSpy be also used as a replacement as syslog? 
12:50:02	 From  Enrico : Can QSpy  work without a UART/USB ? For instance storing data in a ram block and then extracting it through debugger ?
12:53:01	 From  Jay Cosper : or dump it through some other mechanism
12:53:25	 From  Erwin : Thanks for the great presentation. I Love the approach very much. The only drawback to me is it conflicts somehow with "test what you fly and fly what you test" if you remove traces on release?
12:56:25	 From  Erwin : Thanks, really interesting thoughts. Really worth to spent more time on rethinking!
12:57:12	 From  Leandro Pérez : I can't see the video completely… But the approach is very interesting… I need see you another videos to understand the full concept
12:57:38	 From  Susan McCord : thank you Miro! Your presentations are always compelling.
12:58:18	 From  Enrico : Freertos or State machines ?
12:59:17	 From  Leandro Pérez : Good point Enrico... more for constrained devices
12:59:34	 From  Raul Pando : Thanks Miro
12:59:41	 From  Jay Cosper : thanks for the talk
