How to call an instance into layout

Muralidhar
Muralidhar over 8 years ago

Hi,

I am writing a program to call the devices from the technology library (P cells) using the following code

master=dbOpenCellViewByType("cmos28g" "nfet" "layout")    ;cmos28g is the library, nfet is the cell name and layout is view name

paralist=list(list("W" "float" "0.5") list("L" "float" "0.5"))

dbCreateParamInst= (geGetEditCellView() master "instname"  list(0 0) "R0" 1 paralist)

By excuting this program I am getting the instance in my layout but not with the parameters that I specified. It is coming with the same parameters that are in the original layout (i.e., in the cmos28g library layout).

Is there anything wrong in the program ?  (or) Do I need to include anything else?.  Please clarify it.

Thanks.

    I don't think that this can be your code, for example, I see the following typo:
    dbCreateParamInst= (

    The instance name would have to change for each instance also.
    If this is your code then I would not have expected it to work, but anyway, fix the typo above and/or post your real code.
    Good luck!
