Trace hierarchy of cell (schematic view) without open

tyanata

 Hello,

Do you know if it is possible to do following to list all sub-cells ( noy only first level of hierarchy but all levels ) of certain cell without opening it.

 

What is our use case, we want to check if all cells in certain hierarchy are with their last versions.

So let's say I go in Library Manager to the top schematics and select it and then run some procedure to list of subcells of the top schematic.

 

Then we will check one by one each item (cell) of that list if it is managed, and if yes then check if it is last version.

 

Thanks in advance for all posible ideas!

Get a list of cells, the views, and cells instantated

Main entry point is abLibraryRefs(libName)

Updated Sept 2013 since previous code was for 4.3.4!
