Problem #1: Metastability How do you ensure that you have isolated metastability across clock domains so it does not affect design functionality? Problem #2: Reconvergence (correlation) How do you ensure that a group of converging synchronized control signals are in sync at a particular clock cycle? Problem #3: Data hold problem (data loss) How do you ensure that data from one clock domain is held long enough to be captured by the other clock domain? (Fast to slow clock, data enable sequencing)
