gds Analyze the problem #1562

Dear author, I would like to ask how Klayout parses GDS files. If possible, could you please tell me the specific location of the code?

klayoutmatthias commented 7 months ago

That's difficult to say. There is not a single piece of code responsible for reading GDS as there is an architecture behind (parser, database).

But what is the problem you're trying to address here? Or what problem do you wish to solve?

Thank you for your reply. I am trying to parse the GDS layout in Qt using some simple methods. I am wondering if it is possible to use a third-party library to parse the GDS layout. Can you give me some suggestions? In Qt, do I use QGraphicsView, QGraphicsScene, and QGraphicsItem to draw the layout? Could you please give me some suggestions? Thank you very much.

It’s usually helpful to give some background when asking questions. Why do you want to write your own gds reader/datastructure/viewer ?

A simple search in GitHub shows lots of gds2 related projects. E.g. https://github.com/MichaelCache/gds_viewer

Thank you for your reply. The purpose is to try making a demo and learn about this knowledge. Thank you very much for providing examples. Thank you.

@SouthChinaHuihuisauce You may want to try Python - there are some GDS2 related modules, e.g. gdstk and also PyQt5 which is a Python port for Qt. Python is usually easier to learn and to use than C++.

Thank you for your reply. Yes, currently I am also using gdstk. I will try using gdstk in Python. I should first familiarize myself with the file structure of gds2. Thank you again for your suggestion, and I will try it out.
