Purpose: For a custom IP, set the PROCESSING_ORDER property of its _clocks.xdc file to LATE, in order to obtain correct timing constraint processing in the parent design. I use 'report_compile_order -constraints' to verify the processing order in the parent design.
Problem: In the IP Packager GUI, there seems to be a problem when changing the "PROCESSING_ORDER" property of an .xdc file
In case of USED_IN for the _ooc.xdc file, the workaround that I use consists of manually changing the component.xml of the IP (i.e. adding <spirit:userFileType>USED_IN_out_of_context </spirit:userFileType> )
In case of the PROCESSING_ORDER, I couldn't find such a workaround. Example of component.xml containing the PROCESSING_ORDER info ?
