If you perform an IPD-XML Import sometimes the source tool does sum up the die are of its children which is not correct and leads to huge total die areas in medini.
In case you have no glue area which is supposed to be described in the parents die area according to the IPD-XML definition. You may simply delete the die area at the parents.
The script below will allow you to delete the die area value at each container element.
Happy scripting!
