warning when create library

Duy Hien

Hi everyone, 

I would like to ask about a warning in CIW. When I try to create a library which "Attach to an existting techfile" option, the CIW displays warning:

http://www.cadence.com/CSSharedFiles/forums/storage/38/1310402/qrc.inverter_test.log.txt

*WARNING* (TECH-230035): User-defined rule "minExtensionDistance" in constraint
                         group "foundry" of techDB "<tech_name>" conflicts with
                         a built-in constraint with the same name.
                         You may write out "constraintGroups" section to an
                         ASCII file, reopen the technology database in "a"
                         mode, and reload the file to update the database.
                         Another option is to rename this rule.

Can anyone figure out this problem, please?

Thank you so much.

Regards.

    Thank Andrew,

    Can you explain for me what <constraint group "foundry"> is and what <built-in constraint> is? What is "constraintGroup"?
