Different scaling for MOS devices and Path/drawings after CDB to OA conversion

Siladitya

Hi all,

I am using TSMC65 (CNM65GP). I converted a design from CDB to OA using CDB to OA translator GUI provided by cadence.

virtuoso version is 6.1.3.

In the translated layout, I see the drawn paths/recs are shifted for some reason. It might be due to different scaling factors for the MOS and drawings. Any help on how to resolve this issue is greatly appreciated.

An example snapshot is attached.

Thanks in advance,

Siladitya

  • Siladitya,

    I would suggest you contact customer support about this so we can look at the data. It sounds highly likely it's PDK-related, but best if we can take a look. Or you should contact the foundry, in case they have any special migration scripts that you need to run.

    Even then, you might want to use something newer than IC615 ISR1 (which is almost 4 years old).

    Regards,

    Andrew.
