@danghai,

Which tool (along with its version) are you using?

danghai commented 4 years ago

I use questa, and version 2019.4

abdullahyildiz commented 4 years ago

I don't remember experiencing such an issue when I try it on Synopsys VCS. Let me look at the verbose log file of the same case when VCS has been run.

danghai commented 4 years ago

It still has warning. Reopen the issue.
