Clock-Domain Crossing
Designers increasingly use advanced multi-clock architectures to meet the high-performance and low-power requirements of their chips. An RTL or gate-level simulation of a design that has more than one clock domain does not accurately model the silicon behavior related to the transfer of data between asynchronous clock domains. As a consequence, simulation does not accurately predict silicon functionality, risking show-stopper bug escapes due to metastability.Metastability is a phenomenon that can cause system failures in digital devices when a signal is transferred between circuitry in unrelated or asynchronous clock domains. This topic area focuses on advanced techniques to find clock-domain crossing errors before they escape into silicon. -
