cb2oa, missing vias

stuso

 Hi guys, when i translate from 5141 to OA i have some missing vias in my IC6 layout. Our PDK providers have the same process in 5141 and OA so we have only converted the design libs.

Looking at my PDK providers OA techlib it looks more complex regards via definitions, compared to 5141. In the OA techfile i see a standard vias & viaSpecs definition. I tried to manually edit the tech file and put my missing via definitions into these 2 sections but i noticed when i import this hacked OA techfile and dump it back out again that the viaSpec part has reverted to default...i.e my edits are gone, but the standardVias i added are still there. Crucially however when i open the layout with my new hached techfile attached to the lib the vias are still missing. any advice greatly appreciated, if this is a complex process i'll log an SR.

Thanks

Stu

  •  Hi,

    you should file a SR for this since we would need to look at the cdb and the oa techfile.
    Just by adding vias to the validVia section will not help you to bring them back into the
    translated layout.
    Your cdb2oa should have created a log which should have more informations about
    problems found in the translation process. If vias can't be mapped from cdb to oa you
    should see that reported in that log.
