SIL on autosar composition, Different Types error

I have an autsoar architecture model(autosar composition).

At first I created a test harness on the architecture model and wanted to make sil test. I got error it is not supported I shall set the SimulationMode of architecture model to normal and the SimulationMode of the autosar compome below to the SIL. I did it

Then I got the error Different types as below shown

I follow another way as mathwork proposal, Testing AUTOSAR Compositions

At the end I got the same error Different types with no any helpful info what going wrong :(

Hi Xiaohong,

This error is pretty undetailed. Also, it is very difficult to figure out what is happening without analysing the model. I think you should contact MathWorks Technical Support with your model and more details: https://www.mathworks.com/support/contact_us.html

It was a bug in the code generation. After I forced Simulink to generate a global variable. The problem is solved. Anyhow it was not easy to find out where this error happend.
