symbol PCELL extraction issue.

fishbulb15
fishbulb15 over 14 years ago
I have created a symbol, schematic and layout pcell. Everything seemed to be working correctly until I wanted to start LVS-ing the the pcell. I first ran into an issue where it required that my schematic be extracted since last edit. So I followed the instructions here: ___Schematic PCell: Schematic cellviews modified since last extracted___ support.cadence.com/.../ ------->Which seemed to solve that issue. But now I am getting "ERROR: Netlister: symbol of instance modified, please re-extract cell ''." Is there something like : dbCreateProp(pcCellView "schGeometryLastRecorded" "time" getCurrentTime() ) dbCreateProp(pcCellView "lastSchematicExtraction" "time" getCurrentTime() ) to add to the symbol pcell?? How can I get this to work.. Thank you, Mitchell Cohen

    Mitchell,

    There's a risk you might have a symbol different from the instance - and so the connectivity might get messed up. You could set it to "warning" rather than "ignore" - but of course that would require you to actually look at the log file.

    The chances are other things will find the flaws, and in fact the default from Cadence is "ignore" anyway...

    Regards,

    Andrew.
