- Verify that the step sizes are correctly configured in your Simulink model, especially in the 'ModelReference' block named 'Robot'.
- Examine the 'ModelReference' block named 'Robot' to see if there are any configurations or settings that might be causing the step size computation to fail.
- Since you are using a ‘ModelReference’ block, it means your model has multiple referenced models. Make sure that the simulation settings are consistent across all referenced models.

For a project I am trying to convert a Simulink model, XXX, which consits out of XXX_1 and XXX_2 into an XYZ file. However, I keep on getting this error in the build sumarry: "Code generation file does not exist.". You can find the full output here.
XYZ.export('XXX')

Hi,
I understand that you are encountering an error message stating : “Code Generation file does not exist” error.
The error message suggests that the code generation process for your Simulink model has failed as it could not find a required file.
Upon further investigation of the error log, I conclude that the issue is occurring due to the model named ‘XXX’. The specific error message related to this model is:
Error: Simulink Coder Error: Simulink Coder Fatal: Failed to compute step size for TID=[0...1] in 'ModelReference' Block: '<Root>/Robot'
This error message suggests that there might be an issue related to the step size configuration in your Simulink model, particularly within a 'ModelReference' block.
You can try the following workarounds to address this issue:
I hope the insight on the error message and the workaround mentioned helps in resolving the issues you are facing.
Thanks,
Kshittiz
