How do we get all the child cells of a subcell

[joamatab]

c.each_child_cell() does not return all the cells in the hierarchy

how do we get all the cell names in the hiearchy?

        for cell_index in c.each_child_cell():
            ci = c.kcl[cell_index]
            print(ci.name)

[joamatab]

is [ci.name for ci in c.kcl.kcells.values()] the prefered way?

what are all the child cells in the hierarchy? you mean all cells which are in any hierarchy level below the cell? If yes, then https://klayout.de/doc/code/class_Cell.html#method22 i.e. [c.kcl[cc] for cc in c.called_cells()]

[joamatab]

all the child cells for a particular device

the issue with [ci.name for ci in c.kcl.kcells.values()] is that it can be slow

[sebastian-goeldi]

Of course iterating through all cells is slow. Therefore the one above
