Simulink accelerator error: "undeclared identifier"

Hello,

I'm using matlab 2019b update5. I'm simulating a model that contains a referenced model. If I run the referenced model in normal mode, everything is fine. If I put it in accelerator mode, Simulink gives the error below.

Is it a Simulink bug or maybe a setting issue?

Does code generation settings and Simulation target settings have influence on this code generation?

Thanks

I encounter the same issue. Have you got the solution? Thanks

Never found the solution. I didn't try with a newer matlab version. My feeling was that is a matlab bug. What version are you using?
