Hi Jim,
you can use master or any other branch, but without warranty.
The usual approach (and the one favoured by GitHub) is: features are developed in branches. When they are considered stable enough they are integrated into the master (pull request). Hence the master is kind of "latest greatest", but with a certain risk of being spoiled. There are also forks from other user with their own masters and branches. Don't confuse them with the ones from the KLayout project.
But eventually, when the master is considered to have a sufficient quality, a release is made by creating a release tag (https://github.com/KLayout/klayout/releases). A release is a snapshot which is then turned into Windows binaries, Linux packages, PyPI wheels etc. This this is a lengthy process and I don't want to do this too often.

I see .. anyway, I hope the previous answer wasn't wasted :) Yes, there is such a netlist reduction step. It's called "device combination". It's described here: https://www.klayout.de/doc-qt5/manual/lvs_tweaks.html. I introduced the &quo…

@ahmedo Thanks for providing this information I think there is a lot of optimization potential in your script. 19MB isn't really a big file - I deal with GB-size OASIS files on a daily basis. But OASIS can have a hidden complexity: small files may …

Very good :) BTW: in the recent 0.26.10 version, I have included "typing" in the Windows installation. Best regards, Matthias

Hi Jim, I had to look up "stymied" in a dictionary first (I'm not a native speaker), but I hope I understand your question now :) First of all, I need to say that the LVS compare algorithm made some progress in the 0.27 which I am curren…

@ahmedo Sorry, but I can't provide support if you don't provide details. Here are some details you should provide: * Where is time is spent (reading, merging, writing?) * Memory footprint and whether maybe swapping is involved (physical memory exc…

@sebastian Thanks a lot for your assistance. And yes, KLayout's Qt isn't pyqt. The reason is that I started with Ruby about ten years ago and qtruby (the pyqt equivalent, which AFAIK isn't maintained any longer) was not evolved. After integrating P…

Hi Thomas, if you don't care about where a cell is selected in the cell tree, you don't need to analyze the fill selected cell path. The last item is sufficient: lv = RBA::LayoutView::currentcv_index = lv.active_cellview_indexly = lv.cellview(cv_i…

Hi Thomas, I'm sorry, but there is no such event currently. This has to be created first. Matthias

Hi Tracy, thanks for sharing this code and the recipe for installing the extension. Matthias

Hi Frank you can also simple use a block instead of a proc: mw = RBA::Application.instance.main_windowmw.on_current_view_changed do |last| puts "viewchanged #{last.inspect}"end But you're right about the nil. The documentation was inco…

Hi Thomas have you considered the instance browser for this case? Select a cell in the tree and use "Tools/Browse Instances" to get a list of cell placements and walk through that. The highlight style follows the selection, but if that i…

@tagger5896 Thanks too for sharing this ... although I sense some frustration and I can't see your original post. I hope the issues have not been too severe. Matthias
-
@tiboy Very good! Thanks for sharing this and this feedback :) Kind regards, Matthias

I created a ticket for this: https://github.com/KLayout/klayout/issues/709

@acs Thanks for your nice testcase ... it was pretty simple to debug the issue. It's actually a stupid bug. The compare algorithm sometimes enters an infinite loop when it encounters a case of two topologically equivalent (i.e. entirely parallel) s…

Here is some code for a plugin that drags a box: # Register this macro as "autorun" to enable the plugin# This is the plugin implementationclass DragBoxPlugin(pya.Plugin): def __init__(self, view): super(DragBoxPlugin, self).__init__(…

@tiboy The concept of KLayout does not include a right-click context menu. The mouse buttons are reserved for zoom, select and pan/zoom. You can basically implement a right-click menu with a plugin, but doing so puts you outside the basic UI conce…

Why do you use (l - 1) and (l + 1) when computing x and y rather than just l? Matthias

Hi Francesco, please try with a name that includes the file type, e.g. "MEA60_RoutingCorrected.bmp". If that does not work, you can also use ".png". It will be monochrome and I have made some good experience exporting really hu…

Good to hear that's working! :) Thanks, Matthias
-
Yes, very good! Thanks for sharing the code! :) The trick is "layer_view.max_hier". Without that you just get cell frames. Kind regards, Matthias

Hi, thanks for the test case. I'll take a look. Regarding your questions: B. I don't want to maintain two ecosystems. One is already enough effort. And Ruby is better suited for a DSL, so no Python from my side. But the core API is available in P…

Very good! That's example what I meant. Thanks for sharing the code! :) Warm regards, Matthias

Please try "pip install klayout". You can use "import klayout.db as pya" to get the "pya" namespace. But it will just provide you with the layout manipulation API. Matthias

Hi, you're right, the problem is to translate the data into a byte-string in Python. The Qt binding is somewhat aged and was created when there wasn't bytes() and strings have not been so picky about encoding. Right now, the file save/read way is …

Hi Holger, thanks for pointing this out. This is a flaw. I'm afraid there is no workaround. I have created a ticket for this: https://github.com/KLayout/klayout/issues/707 Matthias

Okay. What is available strongly depends in the Python version your KLayout instance comes with. If you want to have a specific version with specific capabilities, you'll need to build KLayout against it. Another option is to use the klayout modul…

First: please format your code. This is hard to read. This forum supports Markdown and comes with a nice editor. So please use it (Paragraph Symbol - code). Second: you cannot just put instances into a region. A region is for polygons. You cannot &…

Hi, last question first: you can use Markdown here. My way to marking code is to separate code by a single like with three backticks. Regarding the "_destroy" question: Basically you don't need to destroy objects at all. In Python and Ru…

I answered some of your questions in the other posts. Maybe these help. Sorry for the delay. I'm kind of busy. Matthias
