dcfifo aclr recovery timming fail

Timing analyzer tool report that Recovery timing on reset synchronizer fail. I found I can apply the following false path assignment on the reset path:

set_false_path -to *dcfifo:dcfifo_component| dcfifo_*:auto_generated|dffpipe_*:wraclr|dffe*a[0] • set_false_path -to *dcfifo:dcfifo_component| dcfifo_*:auto_generated|dffpipe_*:rdaclr|dffe*a[0]

Is it necessary use this to avoid timing violation or is it some another way?
