symbol to layout conversion

frasheed

 Hell0,

I am using  lxGenFromSource(dbOpenCellViewByType(libName cellName "symbol" "" "r") ?layLibName newLib ?layCellName newcell ?layViewName "layout") to convert symbol into layout but I am getting the following warning

 *WARNING* (LX-2031): Cannot find the specified schematic cellview. The name or database IDyou specified either does not exist or does not point to a validschematic cellview. Specify a valid schematic cellview and try again.

but I have this Symbol view in my specified cellname , What could be the problem ?

Thanks

  • " the symbol view has schematic inside"

     This should not be. The symbol is the abstraction of the schematic and should only contain the pin and parameter information (with some graphics). The components and connectivity should be in the schematic. Otherwise, many tools will not work.

    First, check the viewType of the master of the symbol view. The view name can be almost anything but the viewType of a schematic symbol is "schematicSymbol". The viewType of a schematic is "schematic". If the viewType is schematic, your view has an incorrect name and you can save it as a schematic.

     If your viewType is "schematicSymbol", you have to recreate the schematic in a schematic view. Open a schematic view for the cell. Copy the schematic symbol placements and the connections from the symbol and extract the connectivity (Check and Save). This should then work.
