Translating IC6 libaries to IC5

Hi Giuseppe,

oa2cdb is what you want.

Andrew

Hi,

Thanks for your reply, but when I try to use it I have the below error:

  ERROR   (OACDB-113): Failed to find the OpenAccess library "TEST_CONVERSIO"

 I checked the cds.lib definition and it seems ok.

Giuseppe,

I believe oa2cdb requires a lib.def file not a cds.lib file. So here's what I did to make this work:

# starting in my existing directory that contains OA libraries
mkdir CDB
cdsLibEditor -batchWriteLibdefs lib.defs
cd CDB
oa2cdb -cdslibpath ../lib.defs -lib mylib

The cdsLibEditor has a batch mode to convert a cds.lib into the standard OA lib.defs format (similar to cds.lib, but only supports a subset of the syntax).

Regards,

Andrew

Hi,

The problems was related to lib.defs file as you wrote, I fixed it but now after the conversion I have some problem with the pin name:

  ERROR   (OACDB-638): Cannot translate pin "68" for terminal "EN" in cellview    
                     'TEST_CONVERSIO "CELLNAME" schematic' because the CDB    
                     master cellview 'basic ipin symbol_xform' is not available.
                     Ensure that the library containing the master is correctly
                     defined in the CDB cds.lib file. If the master is not yet 
                     available in CDB, translate it from OpenAccess to CDB first
                     and then rerun the translator for the remaining cells in  
                     the library.

Do you have any suggestion?

The _xform views do not convert backward very well. Technically, OA doesn't support magnification of instances. Howerver cdb2oa would create pcell versions of symbols that have a magnification parameter so that magnified instances will show up in OA. This is essentially a hack by Cadence to work around the limitation provided by Open Access. Your best bet is to not magnify anything, then you won't have any symbol_xform views in OA.

To solve your problem, you can search for the symbol_xform instances and replace them with symbol views instead. Then set the magnification property on the new instance (if necessary). The oa2cdb won't do this for you automatically. Basically, I've found the more I deal with the xform solution, the more I want to eliminate any magnification at all in our designs.

Hi,

 I don't know how I can search the viewname... sorry but I'm switching only now in IC6.

 Reagrds,

Giuseppe

I checked again and my problem is about pin name with view name "symbol". It seems the procedure can not covert the pin name correctly.

 ERROR   (OACDB-638): Cannot translate pin "P__2" for terminal "V" in cellview    
                     'TEST_CONVERSIO "CELLNAME" schematic' because the CDB master  
                     cellview 'basic ipin symbol' is not available. Ensure that
                     the library containing the master is correctly defined in  
                     the CDB cds.lib file. If the master is not yet available in
                     CDB, translate it from OpenAccess to CDB first and then    
                     rerun the translator for the remaining cells in the        
                     library.

 Giuseppe,

 Make sure that in the destination directory your cds.lib has any required reference libraries (e.g. basic) defined (sorry, I didn't explain that earlier) - so you'll need basic, analogLib, and any PDK libraries also defined. Actually the message makes that quite clear...

Regards,

Andrew.
