Set cell dont use

archive

I'm trying to forbid some cells to use in Encounter during optimize
just like below:

dbSetIsCellDontUse [dbGetCellByName bfx05pdv] 1
dbSetIsCellDontUse [dbGetCellByName ivx05pdv] 1

But during the optimisatiom FE did still use these cells.
Also when I looked at the dontusecells list, these cells are
defined inside.
Do you have any suggestions?

    After using db command, you must use "setupfootprint" to update the cell's footprint usage prior to using optDesign.

    BTW, some commands may refresh the dontuse setting on your internal command setting. So it is safe to use sdc. If you insist on using db command, you can use it immediately before optimization command.
