WebIn the standard FIFO, data is valid on the cycle after you assert RD when EMPTY is false. In the FWFT FIFO, data is valid whenever EMPTY is false, and reading the FIFO causes … WebAug 5, 2024 · I think asynchronous FIFO actually internally uses gray code counter to pass the write/read address pointer across the two clock domains. You will have metastability issue if more than 1 bit is toggled in one clock domain, but no all the bits are captured by the other clock domain. One 1 bit can toggle in a gray code counter and the value stays ...
