In various embodiments, one or more timing parameters are associated with a path that crosses between clock domains in an integrated circuit, where the one or more timing parameters specify a propagation delay for the path. In one embodiment, the timing parameters may be distributed to different design stages using a configuration file. In some embodiments, the one or more parameters may be used in conjunction with an RTL model to simulate propagation of a data signal along the path. In some embodiments, the one or more parameters may be used in conjunction with a netlist to create a physical design for the integrated circuit, where the physical design includes a representation of the path that has the specified propagation delay."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Propagation simulation buffer for clock domain crossing","description":"Techniques are disclosed relating to detecting and minimizing timing problems created by clock domain crossing (CDC) in integrated circuits.
