I found the move_layer function works well for this purpose. https://www.klayout.de/doc-qt5/code/class_Layout.html#method117

This works for integer and float values, but doesn't work for TypeLayer. Never mind -- it worked the 3rd try...

Thank you.

Hi Matthias, Does this work in the "import klayout, pya" external Python mode? I installed the SiEPIC-EBeam-PDK using PyPI, and try to run the DRC m = pya.Macro.new(drc_script) m.run() and get this error: RuntimeError: Can't run mac…

I found a way: ly.assign(layout) we can delete this question.

Thank you. Similarly, I woud love to be able to configure the properties of the GUIDING_SHAPE layer, which also seems hidden. print(ly.layer('GUIDING_SHAPE')) returns a blank

Got it working! tech = pya.Technology().create_technology('EBeam') tech = tech.load('/Users/lukasc/Documents/GitHub/SiEPIC_EBeam_PDK/klayout/EBeam/EBeam.lyt') The create_technology seems to register the technology in the system. Could you add th…

Hi @Matthias @JinWallner Here is a way to do this: def produce_impl(self): # Load the geometries into KLayout import os dir_path = os.path.normpath(os.path.join(os.path.dirname(os.path.realpath(__file__)), "../../gds/")) file…

If it is a question of accessing all the grain.xml files, what about just queering GitHub for the single file? e.g., https://raw.githubusercontent.com/SiEPIC/SiEPIC_EBeam_PDK/master/klayout/grain.xml Putting the grain.xml file at the top of the r…

thank you.

Thank you Matthias. This is very helpful, and useful for implementing schematic driven layout: Are there any ways of querying the to-be-instantiated cell, e.g., location, rotation, etc? Is there a way to create a call back for when the to-be-inst…
-
Hi Matthias, I see that SourceForge provides an automated synchronization between GitHub and SourceForge. Could that be useful? https://sourceforge.net/p/import_project/github/ When do you anticipate having v0.29 and a new Git integration release…

Hi @Matthias Regarding cleanup(), I find that these orphan PCell variants show up in my layout when I load the GDS file. Namely I save a file with a single top cell, and after opening, there are new orphan top cells. The specific case is a PCell …

Thank you.

Hi Matthias, I modified your code for a Basic.CIRCLE, and found un-expected behaviour. After running, the cell shows up as "Basic.CIRCLE(l=1/0,r=0,n=64)" and I don't see the layout: (Image) Code: import pyapya.MainWindow.instance().c…

Bishal, Here are some notes on how to import your components into SiEPIC-Tools. Again, I suggest starting with an existing PDK (e.g., EBeam or GSiP), and creating new component following the convention described here:
-
Hi Bishal, I'll write up some documentation how to do this. The easiest would be to edit the existing library and put your own polygons in the cells. On the wiki there is a slightly out of date description of the requirements for pins so that snap…

Hi Bishal, We implemented this as a Package for KLayout. In KLayout 0.25, Tools | Manage Package, and find SiEPIC-Tools https://github.com/lukasc-ubc/SiEPIC-Tools It comes with a PDK, called GSiP, and includes waveguides which snap to components.

Here is an example where a png icon is added to the tool bar: https://github.com/lukasc-ubc/SiEPIC-Tools/blob/master/klayout_dot_config/python/SiEPIC/setup.py

Hi ejprinz, I agree that using a Windows Python distribution like Anaconda would be a good idea. I am not a Windows user however, so do not wish to take on the task of recompiling KLayout on Windows... My interest in Windows KLayout + Python is t…

Hi Bishal, Since you are working on photonics, I refer you to our photonics-specific add-ons for KLayout, SiEPIC-EBeam-PDK and SiEPIC-Tools. It is available in Tools | Package Manager, then find these packages. You may also be interested in a pho…

The above forum post is concerning doing it via script. The easiest way is through the GUI: Edit | Mode | Instance (or push Instance in the toolbar) choose the Library = Basic choose the Cell = TEXT click on PCell, then enter your desired Text…

Thank you. This works well for loading the layer table from file.

Hi Matthias, We have successfully added numpy for KLayout-Windows to SiEPIC-Tools (hosted in KLayout Package Manager). It's a never-ending battle though with Windows and the version of Python you chose to compile with as it doesn't come with pip. …
-
Hi Matthias, So I tried your procedure. Downloaded MSYS2 from the web page (msys2-x86_64-20161025.exe) - you mention you can't use the latest version -- is this the wrong one to use? I found older ones here: http://repo.msys2.org/distrib/x86_64/ …
-
Wow, that looks very complicated. I sure like the "pip install numpy" method on Linux and OSX. Seems like there should be an easier way to solve this: a) get users to install a Python of their choice (such as Anaconda), and have KLayout …
-
Thank you. I am indeed trying to size the entire layout (but selection is a good starting point). Is Region what the menu item is using, i.e., will the performance be the same? thanks
-
Thanks Matthias. I agree with your concerns and the need for a true open source initiative. I think what you are doing is outstanding. It may very well be considered as a starting point for standard, though the challenge is that all the companies…

Hi Matthias, I am writing a script to do some sizing and boolean operations on shapes. It works, but the performance is such that I won't be able to use it on anything more than a test structure. Yet when I access the menu Edit | Selection | Size…

Hi Matthias, In the latest KLayout 0.25, is there any functionality that could enable callbacks, as per the original question? Namely, when I move a fixed cell instance, or pcell instance, I would like it to trigger the execution of some code.. T…
