Converting mosaic of syContacts devices from IC5 to IC6 ( cdb2oa )

bnugent

 

Hello all,

 

I have been converting some old designs over from IC5.1 to IC6.1.4.500 and I've found that the via definitions have changed a lot. This is the first time I've had to use the cdb2oa gui, and the conversions were fairly straightforward with one exception. I encounter this warning:

"WARNING CDBOA-644 -- The cellview <cell_view_name> contains a mosaic of syContact devices. The translator does not   recognize the member instances of this mosaic as vias. So, the mosaic will be translated as a mosaic of regular instances."

 

I have filed an SR because I haven't found any discussion on this error on the forums. Has anyone encountered this issue and more importantly has anyone found a solution to this? I'd appreciate any feedback on this issue.

 

 Cheers,

-Brian N.

    Brian,

    I see that you're having a lot of discussion with customer support via SR 42894256 so I won't duplicate the effort of my colleagues in support and try to answer this here.

    Kind Regards,

    Andrew.

    Andrew,

     

    I am having a discussion with customer support and it has been pretty helpful. I didn't realize how differently vias were defined. It appears that I will have to manually fix all of the mosaic of vias because of how they were laid out in IC5.1. Thanks for replying.

     

    Cheers,
