How to check the existence of a layout database in a particular Directory/Library?

IC Layout

 Hi! All, I have two small questions...Please let me know....

If I have a directory structure like this

1. FLIP_FLOP/D_FF/layout  -- How to check whether layout is empty or not?

2. In the same way How to check whether 'layout' directory in 'FLIP_FLOP/D_FF'  exist or not?

Thanks in Advance..

  •  ddGetObj("FLIP_FLOP" "D_FF" "layout")

    will return nil if there's no layout view. What do you mean by "empty"? Do you mean there's a layout view, but there are no shapes or instances within it? Or what do you mean?

    Regards,

    Andrew.

  •  Yes, There is a layout view but there are no shapes or instances.

  • cv=dbOpenCellViewByType("FLIP_FLOP" "D_FF" "layout")
    nonEmpty=cv && (cv~>shapes || cv~>instances) && t
