Hi,
you can check whether the output of your clock gating is implemented as global.
Look into the report:
Fitter -> Resource section -> Gobal & other fast signals
If not and you have some global lines left you can assign the output of the gating cell to global by using the assignment editor.
Kind regards

Hi, pletz. Thank you for showing me the way.
I tried the assignment editor just now, but when I assign the output pin of the gating cell as a global clock, it shew in yellow(The Help tells that the node I am trying to specify is not found in the netlist), But I really found the pin in the node finder! ( The filter is set to pre-synthesis)
And after compilation, the report shows that it is still not using the global routing resource(there is still enough global resource left).
Is it that I should not search that pin in the pre-synthesis netlist? Then which type of netlist should I use to specify as a global clock? Please help me.
Now I have to constrain the output of the gated clock as a new clock in my '.sdc' file. And this time it worked.
