MULTICLOCK DOMAIN SYNCHRONIZATION VERIFICATION

Metastability and Synchronizer - As illustrated in Figure 1, metastability may be present in design utilizing flip-flop. The consequence of CDC is a metastability effect which leads to either functional non-determinism (unpredictability of downstream data, which could also yield to data loss) or data incoherency (when CDC induced delayed latency on subset of bus signals being sent across, causing non-uniform capture event). CDC issues could cause significant amount of failures in both ASIC and FPGA devices. Let’s assess why CDC is a lingering issue, what its impact and the available remedy guidelines to ensure a robust FPGA design.ĬDC occurs whenever data is transferred from a flip-flop driven by one clock to a flip-flop driven by another clock. It is normal to have not hundreds, but over a thousand clock domains interactions. In the FPGA space, the number of interacting asynchronous clock domains has increased dramatically.
