In reply to cgales:
Hi cgales, thanks for the suggestion. Yes I should start using pkgs even in my practice codes for better visibility.
For now I was able to understand the order in which it require to have all files passed to the tool. And included it in my top tb.
I will keep that code there (it’s a very simple skeleton) for now. May be it will help others if anyone faces this issue and can’t understand why.
Thank You
