Accellera Standard Supports Hierarchical Data Model For CDC And RDC Analysis


The hierarchical flow for clock domain crossing (CDC) and reset domain crossing (RDC) is a methodology used in the verification of large, complex digital integrated circuits. It's a divide-and-conquer approach that significantly improves the efficiency and turnaround time for ensuring design reliability against metastability and other issues at asynchronous boundaries. Questa CDC and RDC sol... » read more

Elimination Of Functional False Path During RDC Analysis


Reset domain crossing (RDC) issues can occur in sequential designs when the reset of a source register differs from the reset of a destination register, even if the data path is in the same clock domain. This can lead to asynchronous crossing paths and metastability at the destination register. RDC analysis on RTL designs is done to find such metastability issues in a design, which may occur du... » read more
