CDC Methodology

sureshm

Hi All,

I am using the CCD tool for my CDC methodology. But the information about the commands & the explanations given in the documentation is very limited with respect to the explanation.

I  would like to explain the problem/requirement to see the issues from my deisgn

1) How to mention/get all the signal cross overs in a report which are not passing  through the specified user sync modules?

2) how to specify multiple sync modules to the design/ cdc rule set ?

3) How to generate waiver file and how to feed  the waiver file to the CDC tool?

Any inputs on the CDC methodology is highly appreciated. !!!

 

Thanks

suresh

    - To get the paths that failed a crossing, you can use

    &quot;report rule check <specific> -status fail&quot;

    - To specify multiple sync modules, you have to go into tcl mode and then use

    &quot;set_attribute user_sync_modules [find -design user_sync_module*]&quot;

    The command above will find all designs (modules) with names starting with user_sync_module.

    - To generate a waiver file and use that file during CDC, you can use

    &quot;add rule filter&quot;.

    Once the rule filter is added, the file is used automatically.

    For details about the capabilities and options of these commands, please consult the reference manual. Please make sure you downloaded the latest version of the user guide/reference manual, as the docs have been improved in the latest release.

    Hope this helps!
