Webread or write operations can be performed on the FIFO. The flag logic in the FIFO also inhibits reading from an empty FIFO and writing to a full FIFO. When reading an empty … Web2-stage FF synchronizer. Hello, I'm interseting in knowing more about 2-FF synchronizers. I was reading some posts in this forum and i saw that: When using a two FF synchronizer, the delay between the two Flip flops must be small to let enough time to metastability to reslove. And that's why we use the set_max_delay ( and now ASYNC_REG).

How to create a FIFO in an FPGA to mitigate metastability

WebApr 1, 2011 · A net delay constraint bounds the wire delay between the two clock domains, to help reduce latency through the FIFO. In the RTL example above, the pointers cross clock domains at the ff_launch to ff_meta register path, in two instances of the synchronizer_ff_r2 entity. The following example constraints are appropriate for the RTL above.
