WebIf you annotate the synchronizer activity properly, you can get the MTBF number from the tool and detetmine if 2 or 3 or 4 FFs is sufficient. Since the FIFO is being implemented from an IP core, the tool will manage the application of the ASYNC_REG property to these flip-flops as well as the clock crossing constraints that are required. Avrum Figure 12 Timing for handshake synchronizer. Asynchronous FIFO synchronization. FIFO is best way to synchronize continuously changing vector data between two asynchronous clock domains. Asynchronous FIFO synchronizer offers solution for transferring vector signal across clock domain without risking metastability and coherency problems.
