When I use the "-dict" option with "set_property" in the XDC file, I receive the following message during Synthesis in Vivado 2015.2:
However, I do not have any issue in Vivado 2014.4.
How can I resolve this?
This issue is resolved in Vivado 2015.3.
In Vivado versions prior to 2015.3, if the properties specified with -dict are only used for Implementation, this message can be ignored.
If the properties are also used for Synthesis, you need to re-write the constraint to manually expand it into separate set_property commands for each name/value pair.
