GDS Hierarchy Traversing #264

Hii @heitzmann, can we### traverse hierarchy in gdstk and access cell present in that hierarchy. Example, I have 10 hierarchy in my GDS, can I access the bottom and top hierarchy and move from top to bottom or vice versa and access each cell present in that hierarchy.

Yes, just look at Cell.references. For each reference you can go to the corresponding cell with Reference.cell, and then traverse its references and so on. Note that you might traverse the same cell more than once, if it is referenced multiple times.
