Agnisys Webinar on CDC

As the demand for higher speeds and lower power consumption in System-on-Chip (SoC) designs continues to rise, engineers face the challenge of managing multiple asynchronous clock domains within the same system. Clock domain crossing (CDC) introduces complexities that, if not addressed properly, can lead to metastability and functional failures. In this free webinar, we will delve into effective techniques to avoid metastability when signals traverse from one clock domain to another.

Details of the Webinar: 

Various IP blocks within an SoC are often required to work in different clock domains in order to satisfy the power constraints. Clock domain crossing (CDC) challenges faced by design engineers include:

  • Speed and power requirements lead to designs with multiple asynchronous clock domains on different I/O interfaces and data being transferred from one clock domain to another.
  • Transferring signals between asynchronous clock domains may lead to setup or hold timing violations of the flip-flops in the receiving clock domain.
  • These violations may cause CDC signals to be metastable.
  • Metastability may also arise from jitter between asynchronous clock domains, resulting in functional failures if the appropriate clock synchronizers are not present.


This webinar will examine the techniques used to avoid metastability as signals cross from one clock domain to another:

  •  Mux Synchronizer
  •  Two-Flip-Flop Synchronizer
  •  Handshake Synchronization
    •  Write operation
    •  Read operation 
    •  Pulse
  •  Reset Domain Crossing
  •  Custom Synchronizer


Time will be allotted for Q&A at the conclusion of the webinar.
