How to get the transfom of each instance to its refered cell

sysubeing

I have a layout with such hierarchy. How can I get the transfom of each instance to its refered cell(e.g. K01, K02) in python script?

Hi,

It depends on whether you already have the Instance object or just the referred Cell.

1. If you have the instance, simply use [d]trans or dcplx_trans.
2. If you need to "backtrack" from the cell (e.g., K01), use each_parent_inst to find its parents first.

Is one of these what you are looking for?

In case 2, you can find an application of each_parent_inst at https://www.klayout.de/forum/discussion/2568.
