Constraints not being picked for DCFIFO

Hi, I am having various DCFIFOs in my design. I have applied constraints according to the ug_fifo. Attaching link for the reference https://faculty-web.msoe.edu/johnsontimoj/EE3921/files3921/ug_fif...

Do you have any update?

 

Additionally, Even if it remained, a stuck‑at node does not toggle, so the SDC constraint would not have any meaningful effect. In such cases, it is safe to ignore because the removal aligns with the design intent.

      You may double-check the .rpt report in the text files, as sometimes it is not shown in the GUI.
