Cell is not defined error (maybe an auCdl issue)

oldnick

I'm working on a design that has structures without schematics (CCD cells), effectively the layout and schematic are both empty as far as LVS is concerned. Anyway, I've modified the rule deck so that LVS picks up the structures and recognises each cell and that seems to work fine.

I've been trying to make a schematic symbol for the cell so that LVS sees the cell in the layout and the corresponding symbol in the schematic and can match them. Anyway, I made a symbol with the required in/out pins and did an LVS, which failed. I then copied the symbol view to create an auCdl view, which seemed to get me further through the LVS process but I ran up against this error and I'm not sure what to try next.

ERROR (NVN-13010): Cell CCD is not defined. 

Maybe there is something more to do with the auCdl, I just copied it to an auCdl view in library manager.

Any help would be great cheers.

  • I'd have to do some experiments and checking through the documentation to work through this. Whilst I have a lot of knowledge of Physical Verification in general (dating back over 25 years), I've not done that much PVS rule generation or technology setup so I'd have to do some revision and research...

    Anyway, I've spoken to the Europractice folks, and they've assured me that your issue has been assigned an owner and they will be dealing with it as soon as possible. Rather than double working (and I do this forum in my "spare" time), I'll let them deal with this .

    Kind Regards,

    Andrew.
