How to use "config" or other methods to switch the cell's library during simulation

dogman4

Hi,friends

I have a lib1 cell1 that contains lib1 cell2. I would like to replace lib1 cell2 with lib2 cell2 during simulation without modifying lib1 cell1 itself—using config or another method(The symbol of lib1 cell2 and lib2 cell2 are identical).

Is there a way to accomplish this?

    You can't do this with the hierarchy editor - in fact there isn't really a clean way (or even difficult way) to do this.

    Could you copy Lib2/cell2/schematic (assuming it's the schematic view you want) to Lib1/cell2/schematic_lib2 (say) and then use the hierarchy editor to pick the schematic_lib2 view?

    thanks,andrew

    sorry,I can't.

    Since I don't have permission to edit lib1, and lib1 is updated frequently, so it's not a good idea to copy lib1 to my own folder.

    is there any other way

    If you are running a single simulation in ADE only (no sweeps) then you could open the lib1/cell1 design readonly, and then do:

    cv=geGetEditCellView()
    newMaster=dbOpenCellViewByType("Lib2" "Cell2" "symbol")
    inst=dbFindAnyInstByName(cv "InstNameOfCell2") ; i.e. the instance name that you want to replace
    inst~>master=newMaster
    dbSetConnCurrent(cv)

    Then you should be able to netlist/simulate the modified design (it's modified only in memory). If you have sweeps, it's more of a problem because ADE normally does the netlisting in the background.
