Replace instances in a schematic by other instances

StephanWeber

Hi,

I have a schematic open in Schematic entry, and want e.g. to replace all instances of nmos_3/symbol of tsmc18rf lib to nmos/symbol of bhvLib. No need for property mappings here.

Is there a simple skill code for this?

Alternatively, I can specify the schematic to be used via lib/cell/view. Then having a target schematic as output would be best.

Bye Stephan

  • Do you need SKILL? Use Edit->Replace and search for "master" and search for "tsmc18rf nmos_3 symbol" and replace with the new master "bhvLib nmos symbol".

  • Hi Stephan,

    something like this perhaps?

    foreach(ih geGetEditCellView()~>instHeaders
  when(ih~>libName=="tsmc18rf" && ih~>cellName=="nmos_3"
    dbSetInstHeaderMasterName(ih "bhvLib" "nmos" ih~>viewName)
  )
)


    Best regards,
    Lawrence.

    Will try it!

    The idea is indeed to extend it for maybe 10 types of cells.

    Hi,

    I open my schematic, and put this into CIW:

    foreach(ih geGetEditCellView()~>instHeaders
         when(ih~>libName=="devices_symbols_hv" && ih~>cellName=="pdomos50"
        dbSetInstHeaderMasterName(ih "bhvLib" “pmos_spectre" ih~>viewName)   ) )

    But nothing happens. So I need to press Control-C. Can you see a mistake?

    It would be also good to have a mapping from multiple target cells to a single final cell, e.g. we have different resistor types but I want to map to an (almost) ideal resistor.

    Bye Stephan
