Error of refresh CDF using abConvertComponentParams.il and abInvokeCdfCallbacks.il

George Qin

Hi Andrew,

I am using your skill file "abConvertComponentParams.il" and "abInvokeCdfCallbacks.il" in order to refresh CDF of all instance in schematics of my library "mylibrary".

These are my command:

I run these command in Cadence virtuoso IC5141. My process is NSC90nm.

This is my config file:

But I finally get Error information:

How can I solve this problem?

    I tried your skill file successfully in IC616, Refreshing CDF of umc55nm few month ago. But this time failed

    This is because the callback functions are doing type checking, and so you will need to use actual CDF objects rather than the default behaviour which is to use what I call "effective CDF lookalike" objects. You can do that by specifying ?useInstCDF t in the arguments to abInvokeCdfCallbacks or in the config file use:

    runCallbacks (?useInstCDF t)

    rather than runCallbacks t.

    Normally it's OK to use instance CDF rather than cell CDF (I don't think I've ever seen a case where the CDF callbacks require cell CDF (usually because they check cdfgData->id->... within the code) and they do type checking of the arguments to ensure that the object passed in is genuinely a CDF object (rather than my fake object). That would be extraordinarily unlucky.

    It will have worked for the other technology you used because the callbacks there were not written to do type checking (and to be honest in this case they are checking the type with the type character "o" which means other, so I do wonder why somebody has bothered doing that as "other" is not strictly just for CDF objects; if they'd have used "g" it would have been OK).

    Regards,

    Andrew.
