Hello all,
i'm wondering if there's any way how to tell DC compiler "Whenever you want to use register (DFF) use rather this customized one instead of a regular one (from general library)!".

Regards

Will the set_register_type command do the trick?
 

Well in this case, I will define all other flop as set_dont_use (sdc command), but the liberty of your instance should be "clean" to be used by the synthesizer.
