CDC technique , and why need of CDC

Question

Accepted Answer

CDC stands for Clock Domain Crossing technique used in digital design to ensure proper data transfer between different clock domains.

CDC technique involves synchronizing data signals when crossing between different clock domains to prevent metastability issues.
It is necessary because different clock domains operate at different frequencies and can lead to data corruption if not properly synchronized.
Common CDC techniques include using synchronizers, FIFOs, and handshake protocols to safely transfer data between clock domains.
Example: In a system where a data signal from a slow clock domain needs to be transferred to a fast clock domain, CDC techniques are used to ensure reliable data transfer.
CDC verification is an important part of digital design to ensure proper functionality and prevent timing violations.
