CRITICAL WARNING: [Designutils 20-1280] Could not find module ''. The XDC file will not be read for this module


During Design initialization of Implementation, the following CRITICAL WARNING is observed:

CRITICAL WARNING: [Designutils 20-1280] Could not find module '<module name>'. The XDC file <XDC file> will not be read for this module.


The CRITICAL WARNING indicates that the XDC file cannot be applied because it is referencing a module that cannot be found.

To fix this you must correct the reference for the XDC file (read_xdc -ref <module name>).

If there is no XDC in the project, it is likely to be part of an IP core.

IP core XDC files can be found with the "report_compile_order" command.

Verify if the IP has been correctly instantiated by comparing the instantiation template with the instantiation in the HDL code.
