System Fault Analyzer error

I am trying to simulate multiple faults in a system where I have several step inputs and each of them has a gain fault associated with it. But when I start simulating it, I get the following error:

Unable to simulate fault on inport/outport of block 'Test/STEP1_HYBRID_A_InV' as it is may have been optimized out or substituted during compilation.

What does that mean?

Hi @Aayush,

Thanks for reaching out. I'm sorry you're running into this error.

It appears that the block was treated as a virtual block during compilation, and became "unavailable" during simulation after being optimized.

I recommend contacting MathWorks Technical Support so we can help you directly, and we may have some additional questions.

Thanks again.
