Innovus: getting area value of a sub module from the hierarchy

Hello,

I am trying to get the area value of a submodule from innovus through a script (after importing my design).

My top_module is named grid_clb and the sub module of interest is "grid_clb_0_/fle_0_".

I tried doing the following:

-----

selectObject Module grid_clb_0_/fle_0_

dbGet selected.box_area

But it returns 0x0.

-----

Another thing I tried is to do:

-----

ungroup grid_clb_0_
deselectAll
selectObject Module grid_clb_0_/fle_0_

dbGet selected.box_area

-----

This method works only if I do it manually. If I use a script doing all of those commands through a procedure:

proc get_ble_area {} {
ungroup grid_clb_0_
deselectAll
selectObject Module grid_clb_0_/fle_0_
set ble_area [dbGet selected.box_area]
return $ble_area
}

I basically have to call this procedure twice by hand (since the first time I call it, it ungroups the top module but still returns 0x0 for the area).

If I call this procedure twice in my top level script, it does not work. I still have somehow to call this procedure by hand through the innovus terminal. I feel like I am missing something with using the ungroup command through script.

Would it be another way to proceed in order to get this specific module area?

Thanks,

Edouard
