Trying to convert Simulink model into dll format to integrate it in VeriStand , upon building the simple code I am getting below errors. How can I resolve these error?

### Generating code and artifacts to 'Model specific' folder structure

I I have simple model which is - input *Gain=ouput, I even tried A+b=c

and then using taget file as NIVeristand.tlc and building the code.

after building I am getting below error-

### Generating code into build folder: C:\Windows\System32\trial123_niVeriStand_rtw

Warning:Source 'trial123/NIVeriStand In1' specifies that its sample time (-1) is back-inherited. You should explicitly specify the sample time of sources. You can disable this diagnostic by setting the 'Source block specifies -1 sample time' diagnostic to 'none' in the Sample Time group on the Diagnostics pane of the Configuration Parameters dialog box.

I have the same error, have you solved it?

Hi Ashwini,

From what I understand, you are working with a custom .tlc file supplied by NI, and running into errors while building your model.

The version of Veristand you're using (2021) is not compatible with MATLAB R2022a. Refer to this NI documentation for guidance on version compatibility: https://www.ni.com/en/support/documentation/compatibility/22/veristand-labview-modeling-and-legacy-simulink-modeling-version-.html

Hope this helps.
