How to convert a CDB library to an OA library

Jump to navigationJump to searchCDBCadence Data Base formatOAOpen Access format (now used in IC 6.1 and later)To convert a CDB library to an OA library:

• First make sure that the DFII library is referenced in a cdb.lib file.
• Make a new directory for OA and cd to it.
• Next convert the technology library:
  cdb2oa -lib <techlib> -cdslibpath <path>
• 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:

• Create a temporary directory to work in and change to that directory.
  mkdir $HOME/tmpcd $HOME/tmp
• Create directories cdb and oa directories and change directory to the cdb directory.
  mkdir cdbmkdir oacd cdb
• Create a cds.lib file for the old NCSU_TechLib_ami06 tech library.
  vi cds.libEnter the following:
  DEFINE NCSU_TechLib_ami06 $CDS_SITE_CONFIG/CDK/ncsu-cdk-1.5.1/lib/NCSU_TechLib_ami06
• Change directory to the oa directory.  This can be done using a relative path.
  cd ../oa
• Execute cdb2oa to convert the tech library to the Open Access database format.
  cdb2oa -lib NCSU_TechLib_ami06 -cdslibpath ../cdb
• You should have a message that looks like this.
