Data mux for clock domain crossing

[sachinkhati]

Hi,

I am new to multi clock designs and facing some problems in clock domain crossing . I have gone through the 2-3 FF synchronizer for single bit CDC and have also gone through Async FIFO .

But there is not enough information on DMUX synchronizer which is widely used for multibit CDC. It would be of great help if someone could enlighten me on the DMUX cdc or recommed some documentation.

regards,
sachin

In Atrenta spyglass documents, you will get more details about synchronizer structures.

Even mentor Questa CDC user guide has this information.
