Dataflow Conversion Error when generating hdl code from simulink
显示 更早的评论
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

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.
