Getting Error “Internal error while creating code interface description file: codeInfo.mat. Aborting code generation. Caused by: Invalid index” during code generation.
显示 更早的评论
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.

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

I had the same issue with Matlab 2024b. Deleting temporary code generation files (slprj, etc.) worked to get rid of the error.
