Using OA for netlisting

1heinz

Hello,

I want to use OpenAccess to do my own netlisting.

Accessing connectivity data is no problem.

Is there a way to access CDF information like attribute mapping,

port sequencing and model type ?

 

Regards

  • This is probably a better question for the OA forums on Si2. 

    I believe the answer is that you can access the data via the data.dm "bag" for the cell, but there's no CDF API, so you'd have to interpret the information yourself.

    Alternatively (if it's a C application) you could use the ITK DB (Integrator's ToolKit) API functions to access the CDF.

    Regards,

    Andrew.

  •  Locating the "data.dm" file with OA oaDMContainer class member function is not a problem.

    But how can contained data be interpreted ?

    Is there any documentation about the file format ?

    Regards,

    Heinz.

  • Hello Heinz,

    I would have thought that the answer is "no", since I believe that the data.dm file is proprietary - certainly CDF is specific to Cadence, and, like Andrew said, if there is no CDF API, then you will need to try to intrepret the information yourself. I could be wrong, someone else might be able to post further information on this, the above is just my opinion.

    Regards,

    Lawrence.
