Thanks for helping. I hadn't seen ResetInserter in any documentation and just finished investigating it. I performed a dir() to learn its interfaces. Whereas it has a control_name property containing "reset," this is a string and cannot be driven for the purpose of simulation. As far as I can tell, ResetInserter has no Signals objects. I also saw ResetInserter has a transform_fragment_insert method but its signature is not clear to me. I don't how to use it.
How did you learn about ResetInserter? Where is a reference?
