Simulink/ Stateflow crash when running model in accelerator mode on 2020B - failed assertion

Hello

I have a model which references many other models, this runs fine when I simulate in normal mode, but when I choose accelerator mode one referenced model crashes and therefore the top model willl not run. I get the following error. No idea what it means. The particular model handles a ton of inputs, I tend to think that has something to do with it. Any pointers appreciated!!

Cheers

Richard

If you are seeing a crash I would suggest sending in a Crash Report or contacting support. Sharing your model if you are able to, either here or when contacting support, might help in identifying and resolving the issue you are running into.

[Richard Good]

OK thanks, I raised a case. Not had much luck with accelerated mode, hopefully support can help.

[Raphaël]

Hello,

I have the same issue in 2020a. Do you now have an answer?

Sincerely,

Raphael
