can i ignore warning ?

how can i fix this error ? and warnings

merci

  • The internal description of stdViaDefs does not support purposes other than drawing. I would add the LPP: PDKREC drawing to your techfile, modify your symbolic contacts or cdsVias to use this LPP. Re-translate and see if you get the error. Since the error message is not verbose, I would start with that.


    If you must have the LPP PDKREC, wellbody, you will have to create a customViaDef which can have the proper LPP.
