Gray codes are used in such case because the empty and full conditions are defined by comparison between the FIFO read and write pointer, however the read and the write process run on different indpendent clocks, if the comparison is made between binary counter false glitches might occur … WebDec 24, 2007 · 15. Formal verification helps catch gray-encoding failure. In case the converging signals cannot be Gray-encoded, change the synchronization scheme to one which uses a common control signal, for example, MUX recirculation, FIFO or handshake. These schemes still need to be validated for proper functionality as described in Step 4. …
