In the Vivado IDE I see "DIFF_TERM_ADV" has a value of "TERM_NONE" in the "I/O Ports" tab for the clock input "sys_clk_p". However, when I run the following command in the Tcl console, I get an empty value: get_property DIFF_TERM_ADV [get_ports sys_clk_p] ...
As noted, defining DIFF_TERM via the XDC file will ensure the implementation tools operate correctly and will over-ride any attribute set in the HDL. When internal differential termination is NOT desired use the following: set_property DIFF_TERM_ADV TERM_NONE [get_ports LVDS_P_PORTNAME] ...

In UltraScale and UltraScale+ designs generated with Vivado versions up to and including 2016.1, the DIFF_TERM attribute is not reported appropriately, nor is the attribute properly checked to ensure that a valid bank voltage is used when the attribute is defined in the HDL as TR...
