I have a scripted project flow.
After the synthesis run has completed, I open the Vivado GUI and insert a debug core.
I then select to save constraints before exiting the GUI.
However, the following error is issued.
ERROR: [Constraints 18-461] Could not find constraint files /eda/proj/proj.srcs/sources_1/ip/dpram_128x72_wrap/dpram_128x72_wrap_ooc.xdc... Design will not be saved. Please use write_xdc or write_ucf command to examine the constraints<
ERROR: [Common 17-39] 'save_constraints' failed due to earlier errors.
The XDC file in question is embedded within the IP DCP and not the target XDC.
Why is Vivado attempting to save the constraints to an irrelevant XDC file?
