Ultrafast CDC checks do not check from "no clock" to a clock

[johnblaine]

Primitives like the MMCM generate signals where the clock is not modeled by Vivado. E.g., Locked. This should be covered by a CDC when it is used.

Thanks.

David, did you look into this? I don't know if you should own this - perhaps we should assign this to johnblane to fix? ;-) It might also be covered by the new report_cdc tool

Hi folks,

Yes I could own this. Not sure what the process is though.

Hi John,

Thanks, that would be nice.

I suppose that one way would be:

1.  Check whether report_cdc already covers the request or not. You might still have the testcases for the issue you reported.
   

2.  Follow instructions from Online Wiki https://github.com/Xilinx/XilinxTclStore/wiki/Xilinx-Tcl-Store-Home . The starting point would be the Contributor Setup Steps followed by Modify an App in the Repository or Adding a New App to the Repository that might have few more information inside
   

By following the instructions, you will get from GitHub the latest version of the script.

I can help you if you have any question.

Thanks,
David
