About the "set_false_path" command

It would be helpful if you could tell me about the options of the "set_false_path" command. 　1)It is explained that the -setup,-hold option specifies Setup(Recovery) and Hold(Removal) as False paths...

    My apologize for not understand your previous question correctly.

    Correct me if I am wrong. This look like asynchronous input to the synchronizer logic.


    Setting false path to the [asynchronous input paths to synchronizer logic] (path 1) should be sufficient.

    Thank you for answering.

    Thank you for responding to my repeated questions.

    I was told that all I had to do was set the phallus path for path 1 in the diagram I presented last time, so I recognized that the following description was OK.

    set_false_path -from [get_ports {data}] -to [get_pins {reg1|datain}]

    If there is no problem, I would appreciate it if you could let me know.
