How do user know IP or BD build-in constraints and prevent double constrain action in user's USER.xdc file?

IP/BD constraints take care of any prioprity or conflicting issues that might happen with the user constraints.
Ideally user does not need to care about the constraints for IP/BD, just needs to add constraints for user logics in user.xdc.

Check constraint file processing order:
Also check Constraint Files Order with IP cores.
