I have some schematics in the OA version 6.1 and I need to read them in the earlier Cadence version of 5.1.41. Is there a way to do this? Copying them and opening them didn't work as the way schematics are saved in 6.1 is different. Is there a script to do the conversion?
There are two approaches that I can think of:
1) Use oa2cdb to migrate the design database back to CDB, obviously you will lose any OA-specific features, but this may not be such an issue for a schematic.
2) Use dbWriteSkill() to output the schematic design in IC61x and then try to load this in IC5141, you will want to give the release appropriately for the IC5141 version for the t_release argument (not sure how this needs to be set, my guess is "5.1"):
[ g_ref ]
[ g_lppString ]
Good luck whichever method you choose.
I am trying to use oa2cdb. I suppose oa2cdb converts OA 2.2 to cdb as it looks for lib.defs file. The library I am trying to convert is still defined in a cds.lib file so I assume this is OA 2.0.
What can be done in this case?
Actually IC61x can use both cds.lib and lib.defs - if you have both then please keep them in sync. I believe that the cds.lib file is the recommended format, but I thought that the cdsLibEditor could create a lib.defs if one does not already exist?
The command-line help for oa2cdb states that -cdslibpath is the path to a lib.defs file, but have you tried a cds.lib file just in case it is supported also?
IC61x does open the existing design which has a cds.lib file so yes, what you say is true. However, the -cdslibpath option doesn't support cds.lib. There may be some env variable that can be changed to disable this. I tried creating my own lib.defs file and it seems to get to the next step. I need to define tech libraries referenced by the design in the lib.defs file as well. The syntax for the lib.defs file seems to be the same as that of cds.lib. Please let me know if its otherwise.
Thanks for your help.
The basic syntax is similar (I understand that cds.lib files can contain more and do more), here's an example (of a lib.defs library entry):
DEFINE pcells /home/user/data/libraries/pcells
ASSIGN pcells libMode shared
I'm not a guru on the lib.defs contents, but the above should be enough to enable a translation I hope,
