Vivado doesn't recognize net that exists

Hello,

There is following constraint in .xdc:

set_property CLOCK_DEDICATED_ROUTE FALSE [get_nets spis_sck_18_IBUF]

Synthesis tool gets this warning:

[Vivado 12-507] No nets matched 'spis_sck_18_IBUF'. ["/home/pyo/proj_Vivado/isg001_logic/isg001_logic.srcs/constrs_1/new/constraints_1.xdc":375]

where 375 is the numeber of line where above mentioned costraint is located in .xdc.

Here is the result of search on nets "*spis_sck*"

spis_sck_18_IBUF_search.png

Any comments ?

Thanks.

Is it recognized if you open synthesized design and run the get_nets command from Tcl console?

Here is what happens when I run get_nets in Tcl console when synthesized design is opened:

get_nets spis_sck_18_IBUF
spis_sck_18_IBUF

So, the net named spis_sck_18_IBUF does exist in synthesized netlist, but isn't recognized  in .xdc.
