Either you or the tool can do replication. You can also set your max fanout to update default value. But I will worry about all these things when the tool fails to meet timing or the design does not work. We depend on these tools and make our living on them and the guys behind them have pre - done much of the work for us to be automated.
If however you do run into fanout trouble then your thinking is right. This is more likely with reset signal than with clock enable.

hello @kaz, yes design doesn't work and i see no timing violations. hence i was trying to add a constraint on the enable to make sure enable reaches the flop on time.
So how do i write a constraint on the enable of a flop in SDC. thanks for your help.
