oa2cdb translation

tkhan

Sorry for cross-posting here and on comp.cad.cadence, I wasn't getting a reply there...

Long story short, I need to translate a design back to IC5141 which
I've started in IC613. I tried the oa2cdb utility on an unimportant
library first, but get the following error:

megatron:/home/student1/guest2/cmrf8sf-cdb> /CMC/tools/cadence/
IC-6.1.4/tools/dfII/bin/oa2cdb -lib exampleVCO -cdslibpath ~/cmrf8sf/
lib.defs
*WARNING* envGetVal: Could not find variable 'dbStatCacheOn'
        in tool[.partition] 'cdba'.
*WARNING* envGetVal: Could not find variable 'dbInstNamingGlobalInc'
        in tool[.partition] 'cdba'.
ERROR   (OACDB-113): Failed to find the OpenAccess library
"exampleVCO"
                     because the library is not defined in /home/
student1/guest2/cmrf8sf/lib.defs
                     or is not readable. Ensure that the OpenAccess
library definition file
                     you specify defines the library you want to
translate and
                     that you have permission to read the library.

INFO    (OACDB-820): oa2cdb translation failed.

exampleVCO is defined in lib.defs

megatron:/home/student1/guest2/cmrf8sf-cdb> tail -1 ~/cmrf8sf/lib.defs
DEFINE exampleVCO exampleVCO

The permissions on the folder are

megatron:/home/student1/guest2/cmrf8sf-cdb> ls -ld ~/cmrf8sf/
exampleVCO
drwx------ 3 guest2 student 512 Apr 12 11:12 /home/student1/guest2/
cmrf8sf/exampleVCO/

Please advise.

Thanks,

  • Hi,

    I need some help in oa2cdb conversion. I want to convert the Nangate open source standard cell library PDKv1_3_v2010_12. The base kit associated with it is NCSU-FreePDK3D45-1.1 . Can anyone kindly guide me on how to successfully convert the library from .oa to .cdb ?

    After using the following script I get these errors :

    SCRIPT:

    cdsLibEditor -batchWriteLibdefs lib.defs

    oa2cdb -cdslibpath ../lib.defs -lib NangateOpenCellLibrary
