In this video, we explore CDC (Clock Domain Crossing) using Gray Encoding, starting with a 1-bit 2-flop synchronizer and understanding its role in safe data transfer between different clock domains. We discuss critical issues like reconvergence/coherence problems, which arise due to varying delays in multi-bit signals, leading to potential metastability and incorrect data capture.
Gray encoding helps mitigate these issues by ensuring that only one bit changes at a time, reducing the risk of corruption when crossing clock domains.
Stay tuned for the next video, where we will dive into the RTL implementation, simulation, and post-synthesis analysis of this concept!
