Error when I using buildCalib​rationBits​tream with Kintex-Ultrascale

My matlab version is 2023a, vivado version is 2022.1

I am try to walk through the example Deep Learning Processor IP Core Generation for Custom Board.

I follow the example exactly, but when I execuated the code

bitstreamPath = buildCalibrationBitstream(hPC);

I have an Error as follows

Could not apply model's setting to the Target Interface Table in Task 1.2 of the HDL Workflow
Advisor for the following reason:

Cannot connect to model 'loopback_external_memory'; please try Update Diagram (Ctrl-D).

Default or last valid setting is applied instead.

If you are using the HDL Workflow Command Line Interface, consider making these changes in the HDL
Workflow Advisor and using 'Export to Script...' to automatically generate the appropriate
'hdlset_param' commands.

I am sure that the reference design regestration files are same as those in the example.

What can I do for trouble shooting?

Hi,

Here are some troubleshooting steps you can try:

1. Close the HDL Workflow Advisor and your model.

2. Restart MATLAB.

3. Remove the "slprj" folder that belongs to your model.

4. Open your model.

5. Update the model (CTRL+D) before you open HDL Workflow Advisor.

Hope it helps!

Thank you so much.

I tried the step 1. 2. 3. but does not work.

However, I feel confused for step 4. because there is not any model (I thought it means a simulink model? ) actually. Becasue I am trying to build a calibration bitstream from M file.

But, I think the reason I fail to execute the code above is that there should be a model. Maybe its name is 'loopback_external_memory', just as what is shown in the error report.

Afterall, thanks for your help. I will try to find it out
