Encounter DEF file export

rayz

I am trying to export my layout from Encounter to Cadence DFII ennvironment using DEF format.  Apparently the DEF file generated by Encounter does not contain all the VIA definitions or Virtuoso has problem reading them since when the design is imported in Virtuoso some of the VIAs are missing and I see warniong message that VIA definitions are missing. Do you have any experince dealing with this issue.

Thanks

     you can retain some of the prop. (inst name, net name..) by adding some key words to the SOCE stream out mapping table.  It is a little tricky to get the DFII tech file to match with the P&R vias defination.  That is why GDSII is a prefered way that DEF.
