How to convert a CDB library to an OA library

CDB

Cadence Data Base format

OA

Open Access format (now used in IC 6.1 and later)

To convert a CDB library to an OA library:

1. First make sure that the DFII library is referenced in a cdb.lib file.
2. Make a new directory for OA and cd to it.

3. Next convert the technology library:

   cdb2oa -lib <techlib> -cdslibpath <path>
   

4. Then convert the library of interest:

   cdb2oa -lib <library> -cdslibpath <path>

For example, to convert the NCSU_TechLib_ami06 tech library from IC 5 to IC 6.1 do the following:

1. Create a temporary directory to work in and change to that directory.

   mkdir $HOME/tmp
   cd $HOME/tmp
   

2. Create directories cdb and oa directories and change directory to the cdb directory.

   mkdir cdb
   mkdir oa
   cd cdb
   

3. Create a cds.lib file for the old NCSU_TechLib_ami06 tech library.

   vi cds.lib
   

   Enter the following:

   DEFINE NCSU_TechLib_ami06 $CDS_SITE_CONFIG/CDK/ncsu-cdk-1.5.1/lib/NCSU_TechLib_ami06
   

4. Change directory to the oa directory. This can be done using a relative path.

   cd ../oa
   

5. Execute cdb2oa to convert the tech library to the Open Access database format.

   cdb2oa -lib NCSU_TechLib_ami06 -cdslibpath ../cdb
   

6. You should have a message that looks like this.
