Hi,

As I understand it, you observe some issue when the DSP Builder in Q19.4Pro. For your information, as I try to replicate your observation in my PC, I encounter issue where my Matlab version is older than yours. I only have Matlab 2018b installed in my local PC and unable to open the slx file that you attached.

Would you mind to help on the following:

1. Please help to elaborate in details on the step to reproduce your observation

2. Just to check with you if this is something can replicated by using any of the example design in DSP Builder? Or only specific to your design?

3. Mind help to export your Model to previous version ie R2018b for me to try opening the file?

4. What is the specific device that you are using?

Thank you very much.

I convert my design to R2018b，and send my design to you
