I try to generate HDL Code form Simulink Subsystem Block and then it shows an error when I try to run from HDL Workflow Advisor in section 3.2 Generate RTL Code and Testbench. Here's an error
Failed Error:Dataflow conversion error: Function2SubsystemConverter.evalExpression: 0: variable description not found for the specified loop iteration

Based on the link you've provided, I've upgraded my Matlab version to Matlab 2023b ver 7. But, I received another error, but it looks like it has the same cause. Here's the error
Error:Dataflow conversion error: PIRGraphBuilder.instantiateSumNode: 0: Index exceeds the number of array elements. Index must not exceed 7.

This unexpected error is encounteded due to sum function with 3D inputs does not seems to be implemented yet in this HDL Coder workflow. I have created an enhancement request to the development team to address this issue.
For now please consider splitting the matrix manually for 'add', you can do something like x(:,:,1)+x(:,:,2)+x(:,:,3) should work.
Please share the model with the respective fix if you continue to run into other issues.
Hope this helps.
