HELP: Warnings on setting technology library name

frasheed

 Hello,

I am writing a short code to set the technology library property of the new library same as the old libraray. When I use the function:

techSetTechLibName(ddGetObj(newLib) oldLib )

 

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x203763a0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1dc20fa0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1d72f3b0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1aa5cbb0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1e57d7c0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1da91fc0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1e567bc0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1d741fd0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1eb66bd0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1d342ff0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1cbd0ff0).

*WARNING* ddGetObjLib: Was passed an Invalid Id (0x1ded2ff0)

 

please can anyone tell me that why I am gettings these warnings ?

     A technology library (techLib) is created when an ascii techfile is compiled into it. A techLib contains the layer and purpose definitions as well as via defs and other technology specific data. In addition, it may have primitive cells such as pcells used in designs. You can tell a techLib because the library directory contains a tech.db file.

    A design library uses the information from a techLib  when creating data for your design. The techLib can be attached (one techLib for the design) or it can be referenced (multiple techLibs support the design - see Virtuoso Technology Data User Guide). If it is the latter, it will contain a tech.db file, the former does not.

    Your error messages look like it is looking for some data which in the original techLib of newLib, changing the techLib makes that data invalid. Do you have any open designs when doing this? It could have stored some data (via definitions, etc.) in VM and now can't find the original references.

    Maybe this is one for customer support.
