FBOUT is PLL feedback clock output

I am tryingto set a global signal to my clk_sys and get error

set_global_assignment -name GLOBAL_SIGNAL clk_sys

ERROR: Assignment is not a global assignment: GLOBAL_SIGNAL -- it is an instance assignment. Specify a global assignment name or use the instance assignment commands.

I also tried

set_global_assignment -name GLOBAL_SIGNAL -entity clk_sys

ERROR: Missing <value> for "GLOBAL_SIGNAL" assignment. Specify the required value.

This is RTL

assign clk_sys = USER_DIPSW1? clk_200_pll : tx_clk_clk ;

What is correct syntax to set a global signal on clk_sys?
