Why do I receive an "Error code 8" when using Simulink Design Verifier?

1 view (last 30 days)
I am using Simulink Design Verifier on my controller model. I verified the compatibility of the model with Simulink Design Verifier, and I am trying to generate test cases for this model. The analysis stopped unexpectedly and returned the following error message:
Error code 8 - internal error

Error code 8 represents an internal error in the Simulink Design Verifier analysis engine.
If you receive this error, contact MathWorks Technical Support. If possible provide a model that can reproduce the problem. If you are unable to send that model, take the following steps to collect information in order to troubleshoot the error:
1. Set the following option on the MATLAB command line:
> set slavteng('feature','DebugLevel',1)
2. Run Simulink Design Verifier compatibility check for the model being analyzed
3. The compatibility check will generate a *.tecla file for the model. Information in this file can provide clues about the root cause of the problem.
The other piece of information is analysis settings. Here is how to retrieve the settings:
1. Get Simulink Design Verifier options for analysis by executing the following command from the MATLAB command line
>> opts = sldvoptions(model);
>> get(opts)
Finally, include *.tecla and options displayed in the MATLAB command prompt.
