*All global resets should be generated within a unique reset management module (RMM).*
*A dedicated RMM brings a lot in terms of reuse and portability. Because all vendor-specific reset elements are generated within the same module, it is easier to replace this module to target other FPGAs.*

*A reset domain is considered as global if:*
  - *It is used in several modules.*
  - *Or it is used in a single module and by at least 20% of the flip-flops in the design.*
