search and replace - box by center x/y

csrockley1

Hi - I am using search and replace often. It can find / replace / delete boxes by area, perimeter, width or height.
Would it be possible to add center x/y as find parameters?
This would be very useful when counting # boxes within a certain wafer size, allowing to delete boxes that fall outside the wafer.
Thanks and regards,
Cristian

Hi Cristian,

You can use custom queries to achieve this.

For example this query will give you all boxes on layer 15/0 whose center (as seen from the top cell) is in a vertical band between 10 and 20 µm on the horizonal axis. Please not that you can use variables inside the "where" expression to simplify the formulas:

boxes on layer 15/0 
  from instances of .. 
  where (var box_in_top = shape_bbox.transformed(path_trans); 
               var xcenter_in_um = box_in_top.center.x*layout.dbu;
               xcenter_in_um < 20 && xcenter_in_um > 10)
