WebLittle work has been attempted to tackle clock domain crossing (CDC) verification signoff of large system-on-chip (SoC) designs. Examples of CDC Issues: 1) Data Loss in Fast to Slow Xfer. 2) Improper Data Enable Sequence. 3) Re-Convergence of Synced Signals. 4) Reset Synchronization. Webers cross clock domains to compute empty and full flags. You Gray-encode the binary counters, trans-fer to the other domain, and then convert the counters back to binary before using them. Occa-sionally, designers access pointers in a FIFO block to do empty/almost-empty or full/almost-full flag calculations. This practice may create CDCs, con-

WebWhen you send a single-bit signal from one clock domain to another clock domain (asynchronous), you SHOULD synchronise it to the destination clock domain to avoid metastability. For this purpose, We have to use flip-flop synchronisers. Traditional way is to use 2-flop synchronisers. WebA synchronizer is a digital circuit that converts an asynchronous signal/a signal from a different clock domain into the recipient clock domain so that it can be captured without introducing any metastability failure. However, the introduction of synchronizers does not totally guarantee prevention of metastability.
