Sync_FF permit to synchronize a signal A in the clock domain clk. Normally, the A signal must be the output of a FF cloked in an other domain. You shouldtn't have "logic" between the 2 domain.
You can configure the FF number (default 2). This number is depending of the MTBF(Mean Time Between Failure).

SYNC_VALID_BIT permit to synchronize a signal sin from clock domain clk_in in clock domain clk_out. The sin signal is clocked with one FF in clk_in domain and NB_FF_OF_SYNC in clk_out domain.
You can configure the FF number (default 2). This number is depending of the MTBF(Mean Time Between Failure).
