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 WebApr 1, 2011 · Dual Clock FIFO Timing Constraints. 1.4.4.2. Dual Clock FIFO Timing Constraints. If you choose to code your own dual clock FIFO, you must also create appropriate timing constraints in Synopsis Design Constraints format ( .sdc ). Typically, you set the read and write clock domains asynchronous to each other by using the … WebSimulations show that our proposed 2-DRO synchronizer reduce the LER (explained in Section III) of data in the read domain by a factor of 1000 over the baseline FIFO . Moreover, for a 10-stage FIFO, the JJ-area of our proposed design is only 7.5% higher than the naive counterpart. cx-5 japan
