FSM_NoDeadlock - Explored (IFV)

Buvna

Hello,

I've been using the IFV tool for quite sometime now and I notice that when I run FSM assertions under AFA, No deadlock assertions remain explored while the others pass easily. Is there anyway to improve this?

Thanks

  • Hi,

    besides increasing the effort and partitioning the design there is not much you can do. Note that the FSM NoDeadlock check is a very complicated check that has to verify the FSM in context of all other state bits as well as excluding unfairness on all inputs.

    There is a change in FSM NoDeadlock checks starting in 13.1 that will improve performance significantly, at the cost of failures due to unfair input behavior. I recommend to try that and share the experience.

    Jörg.
