Detecting objects outside TOP LEVEL layout cell; Virtuoso, prBoundary OBJECT

Cadence Support provided an efficient solution for the case. Below is the SKILL code for the community benefit.

-------------------------------------------------------------------------------------------------------------

/*

You can use the attached SKILL code in the layout window. It creates a menu item with the different submenus under it as shown in the below snapshot.

1. Load the SKILL code in CIW:

load "CCScheckOutsidePRB.il"

2. Open Desired Layout in Layout-L or Layout-XL mode a new Menu 'DOB', gets added with the following choices as defined by the 'CCSUserPostInstallTriggerDOB'. Click on the Check Data Out of prBoundary option to create the markers in the layout design.

2.1. "Check Data Out of prBoundary"

2.2. "Find Marker by Zoom"

2.3. "Explain Individual Marker"

2.4. "Delete All Markers"

3. Click on the "Find Marker by Zoom" and select the zoom to marker option to move to the specific marker.

4. Menu item "Delete All Markers", deletes all the markers in the design.

You may need to change the following two variables in the SKILL code as per your technology to define the purpose and layers to search for and avoid while checking;

validPurpose = list("drawing" "pin")

inValidLpp = list("text")
