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

     Hi Kari,

     I am trying to export GDS file from encounter into DFII. I have cds2gds.map and gds2cds.map, they are pretty similar, which one should I use? also, I found the map files are not acceptable by encounter while doing export. From the document, it seems encounter's layer mapping file has the different format than the DFII mapping layer format.

     THis is from encounter,

    METAL1    NET           1        0
    METAL1    SPNET         999      0
    METAL1    PIN           1000     0
    METAL1    LEFPIN        2000     0
    METAL1    FILL          3000     0
    METAL1    VIA           4000     0
    METAL1    VIAFILL       5000     0
    METAL1    LEFOBS        10000    0
    NAME      METAL1/NET    20000    0

     And this is from DFII,

    #Cadence layer    Cadence layer    Stream layer    Stream data
    #name             purpose          number          type
    #
    metal             drawing          13,10,18        0-63
    poly              drawing          40              0

    so I could not do export and import correctly, any suggestions?

    THanks a lot!
