I am trying to pass some data between two atomic subsystem using a Bus.
When I am trying to generate the code getting the error “Internal error while creating code interface description file: codeInfo.mat. Aborting code generation.
Caused by:
Invalid index”.
If I dont use bus and only use outport to directly exchange, then the code generation is not giving any problem. Pleas help.

I understand that you are encountering an error during code generation in Simulink related to an "Invalid index." The issue encountered is a known bug in MATLAB release R2021a. You can find more information about it here: https://in.mathworks.com/support/bugreports/2637595
To address this issue, I recommend updating your MATLAB installation to the latest version, as the bug has been resolved in recent updates.

Hi Dhruv , As can be seen from the comments below, it seems we will also encounter this issue in 2022b and 2023a. Is it because there is an issue with our Simulink model? Or this bug has not been completely resolved.

I am too facing simillar issue using autosar coder in 2022b version simulink ut it goes away if i use ert.tlc.
The error is:
Internal error while creating code interface description file: codeInfo.mat. Aborting code generation.
Caused by:
  • Index exceeds the number of array elements. Index must not exceed 0.

I have the same problem with 2023a. Is this bug fixed? What is the workarond? Not using mux is not an option for me as I am dealing with a very large model with a lot of muxed signals
