  • Re: CDC functional checks are not validated for design.
     Thanks for the example Clay, I was missing the validate statement after adding the functional checks, the problem was solved on adding the statement. I had removed it due to an error i was getting ealier with Clock analysis failure but now the flow seems to work just fine.   Thanks again. Regards,

  • Re: CDC functional checks are not validated for design.
    Okay, I understand that the functional checks will not be performed for CDC paths that have failed structural checks but in this case there seems to be functionally unvalidated CDC paths which cleared structural checks, shouldn't these paths be validated for functional checks? The problem I'm facing is that even though there are a lot ...

I would like to know why these functional checks aren't being ...

  • Adding clock to CDC tool which is not a primary input but internal to design.
    Hello, I would like to know how do we specify internal clock pins (output of PLL internal to design) to the CONFORML tool for doing CDC checks as the 'add clock' command accepts only primary inputs as definable clocks. The design I want to perform CDC on, has clocks as inputs to the design as well as some clocks which are generated ...
