Warning (332043): Overwriting existing clock: altera_reserved_tck

I didn't have this warning until I add SDC file into my project. I have used derive_clock_uncertainty, write_sdc –expand command to get SDC file.

then re-compiled the project.

I got this warning and I have no clue what it's and how to solve it even I have searched internet.

 

here is something related to altera_reserved_tck in SDC file, not sure it helps or not.

create_clock -name {altera_reserved_tck} -period 100.000 -waveform { 0.000 50.000 } [get_ports {altera_reserved_tck}]

set_clock_uncertainty -rise_from [get_clocks {altera_reserved_tck}] -rise_to [get_clocks {altera_reserved_tck}] 0.020
set_clock_uncertainty -rise_from [get_clocks {altera_reserved_tck}] -fall_to [get_clocks {altera_reserved_tck}] 0.020
set_clock_uncertainty -fall_from [get_clocks {altera_reserved_tck}] -rise_to [get_clocks {altera_reserved_tck}] 0.020
set_clock_uncertainty -fall_from [get_clocks {altera_reserved_tck}] -fall_to [get_clocks {altera_reserved_tck}] 0.020
