gds streamins in CDB and OA, interchangeably

Hi all,

We have designs in CDB as well as in OA (Cadence 6.15) and for some reason we could not use the conversion scripts between databases. Instead we wanted to stream out OA design as gds and read in (stream in back) in CDB for top level integration.

However it has problems and it reports to specify the rod directory, so,

During gds streamout from OA it reports a warning among other translation info :

WARNING (XSTRM-154): The object map file does not contain any mapping for the OpenAccess object 'Marker' and the sub-object 'annotation'. Therefore, these objects in the design will not be translated. To enable the translation of these objects in the Stream file, provide a valid mapping in the object map file. For details on the format of object map file, refer to the "Design Data Translator's Reference" guide for XStream.

So this gds (made above) is the streamed in back to CDB, where it reports the follwing message after translating a few basic cells (gates etc.)

WARNING (315): ROD directory used during Stream In is not the same as the directory defined in the input Stream file. Some information might get lost.

Could anyone give a clue about a possible solution ?

Regards,

Aamir

It's not surprising that this doesn't work because the stream interface in OA versions (IC61X) does not support preservation of ROD objects or pcells (it was of somewhat limited usefulness, because it only really supported a round-trip if nothing changed in the stream files or the environment). So you can't generate the ROD directory during stream out from IC61X and therefore it makes no sense to specify the ROD directory when streaming it back in in IC5141.
There are no plans to add back support for this functionality into IC61X. As I said, it was of limited usefulness in practice.
Regards,
Andrew.

Don't specify the ROD directory on the options form then.

I did a bit of searching, and as outlined in the Forum Guidelines, it would have helped if you'd provided the subversion you're using (as in Help->About in the CIW).
My guess is that you're using an IC5141 subversion prior to 5.10.41.500.5.124 - because I found a CCR (Cadence Change Request) 566223 which describes the symptoms you're seeing- you don't fill in the "ROD Directory" field, and then stream in crashes with a core dump. If you use a subversion higher than 5.10.41.500.5.124 (or USR6 or later) - then it shouldn't happen.
Which subversion are you using? Use Help->About or type getVersion(t) in the CIW.
Regards,
Andrew.

yes, you're right, it's subversion 5.10.41. And how avoid this problem in my subversion?
thank you for your answer, Andrew.

That's not the subversion - that's the major version number. It's the bit after that which matters. Please type getVersion(t) in the CIW and then post the complete string it returns (including the .500 bit).
Anyway, I'm not sure there's a workaround. You should install the latest hotfix of IC5141 which is available on downloads.cadence.com.

Andrew
