New ContributorWays to handle CDC
Hello All, I am new to Altera and I am using Agilex to do some interesting stuff. Does any one know whether Quartus Prime 20.4 have a macro to do Clock domain crossing either for signle bit or multi bits? If not, what is the best way to handle it? Shall we write explicitly write 2 or 3 flops to do synchronization and is there any constraints necessary to be added?
As a starter, you can refer to this video to learn more about CDC. Link: https://www.youtube.com/watch?v=BNiXxmQlCCs
Quartus Pro has Design Assistant(DA) that will help to identify CDC issues and the tool will provide recommendation on solving it.
Since you are getting started, I recommend to use the latest Quartus Pro version 23.4 as the tool has more DA rules and bug fixed.
Regards,
Richard Tan
