Reading GDSII layouts

P: n/a
Hello,
I am looking for a library for reading GDSII layout files structures (hierarchy, cells names, ...).
I found IPKISS (http://www.photonics.intec.ugent.be/...s/default.htm),
but it looks to be a generator and not a reader.

Thank you,
Vincent

The link you gave states this near the top:
IPKISS is a python-based library for the generation of GDSII layouts,
including hierarchy.
It has grown out of the GDS_KEY library, but it is more flexible and
object oriented. Contrary
to GDS_KEY, **it can read and edit existing GDSII files**.

And at the bottom of the page:
* Import of existing GDSII files into a layout (import.py)

It looks to be a reader?!

Funny, I started writing one this past weekend as a learning exercise
(handling large files and start to use classes). If ipkiss does not
work out, let me know specifically what you need and maybe my hack will
work.

Yes, you are right, but I am actually looking for a library that would display
only cell references, and not load the entire design (what will be too time
consuning with Python). And this doesn't look to be present in IPKiss.

Well, if you know how to extract cell names and references from a GDSII
layout, that would be usefull. Perhaps can you send me your code if you don't
mind and I will try to do something from it ?
