Invalid MEX-file The specified module could not be found (DSP Builder Advanced Blockset)

Hello,

I use MATLAB R2022b with Quartus Prime Standard 19.1 and DSP Builder 19.1. But it does not work as expected. Here is what I do.

Open “DSP Builder – Start in MATLAB R2022b_x64”

Open Simulink

DSP Builder – New Model Wizard

MATLAB Command Window tells me

Making new model of type Fixed-Point IP (simple testbench)...A copy of the original file "test1.mdl" has been created because it was last saved in an earlier version of Simulink. To recover the original version, rename the file "test1.mdl.r2013a" as "test1.mdl".

Error while obtaining sizes from MEX S-function 'mip_chanview' in 'test1/ChanView'.

DSP Builder – New Model Wizard – Output shows

Error from MATLAB: Error while obtaining sizes from MEX S-function 'mip_chanview' in '<a ref="matlab:open_and_hilite_hyperlink ('test1/ChanView','error')">test1/ChanView</a>'.

Sometimes it shows instead

Error from MATLAB: Error while obtaining sizes from MEX S-function 'mip_control' in '<a href="matlab:open_and_hilite_hyperlink ('test1/Control','error')">test1/Control</a>'.

Open test1.mdl

Click on “Hardware generation is on / Automatic testbenches are on” to open the "DSP Builder for Intel FPGAs Blockset – Settings"

Click OK (with or without changing the settings)

Matlab Command Window

Error using ControlInit
Error while obtaining sizes from MEX S-function 'mip_control' in 'test1/Control'.

Error in dspba.SettingsLaunch - Show complete stack trace
Caused by:
Error using ControlInit
Invalid MEX-file 'C:\APPS\Altera19\quartus\dspba\Blocksets\BaseBlocks\windows64\mip_control.mexw64': The specified module could not be found. - Show complete stack trace

With “Dependency Walker” I found out, that multiple dll’s are missing . There are so many missing, that I can’t add them manually. How can I fix that?

By accident I found out that the error disappears, when I first run the model and the open&OK the settings. But then I get instead the following warning in the MATLAB command window

Warning: Error parsing: unable to open primary document entity 'C:/Test_DSP1/test1_params.xml'

> In ControlInit
In ControlInit
In dspba.SettingsLaunch 
Warning: Error parsing: unable to open primary document entity 'C:/Test_DSP1/test1_params.xml'

> In ControlInit
In dspba.SettingsLaunch

What does that mean?

Thank you for your support

Unfortunately, the issue appears to be with the DSP Builder tool which is external to MathWorks. You may want to reach out to Intel technical support for further assistance with this issue. You can refer to the following link to access Intel support:

https://www.intel.com/content/www/us/en/support/programmable/support-resources/support-centers/dsp-builder.html

From our experience in Tech Support, issues are often caused by incompatibilities between the DSP Builder tool version and the used MATLAB version. Refer to the DSP Builder Release Notes for more information:

https://www.intel.com/content/www/us/en/docs/programmable/683322/21-3/system-requirements.html

From this link, it looks like the latest MATLAB version supported with Quartus 19.1. is MATLAB R2018b. You appear to be using a much newer MATLAB R2022b. We recommend using MATLAB R2018b instead:
