Translating IC6 libaries to IC5

gparasiliti

Hi,

Is there a way to downgrade an IC6 library to IC5? I know it's strange buit in some case it should be the best way to reuse some IP.

Regards,

  • 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.
