Not sure how to get it back down to a reasonable size. Any suggestions?

Thanks Mike

How can I hide the "Editor option" Box in KLayout when I already have it and use the "layer tab" on the right to select a layer to create a new polygon or erase it?

Although I've tried collapsing it and pinning it to the left whenever I select Add => Box or Erase => Box, I still find it cumbersome and unnecessary.

In order to increase my work speed, I've added and changed a lot of keyboard shortcuts for KLayout. For a better overview I also created a keyboard overview:

If one wants to use the same keyboard layout you have to overwrite the line in the "klayoutrc" file with the following code:

P.S.: If you know how to scale down the image, let me know.

So wanted to ask is it supported?

If yes then how can i do that?

Soo Long time not on this forum.
We are making now in my team a large usage of the package management and technology management tools and this is really convenient and powerful (with the exception of not being able to use it on a github with login/password required, but that's not a big issue)
However in our packages we need few more directory that the one created in the templates available. We wan't these directory to be created "automatically" when we create a new package. I digged in the klayout directory (windows, compiled) to find files describing these templates, but no luck.
Is it possible to create our own package's template?
What is the format used and how is it coded ? Is there a sample file available? or can this be done through scripting?
If it's possible to create these templates, where should the file be stored?

Regards
Joël

But I dont see any subfolder named libraries.
My directory is as such: C:\Users\zakaria.37\AppData\Roaming\KLayout
There are folders and files there which I have attached a photo of.

Could anyone please help me with this? I am very new to Klayout

Is the code for the "TEXT" PCell available somewhere?

Cheers,

Tomas

• the database units (dbu) are the same,
• both layouts are flattened,
• the polygon coordinates are identical,
• all shapes are rectangles.

• After clicking on "Instance > Object Editor Options > ...", the "Select Cell" window opens under the mouse cursor, with the north of the window under the mouse cursor.
• I often have a long list of cells and I often want to unselect the "Show all cells" button.
• But this choice-button is at the bottom of the window... There would be less mouse travel if the "Show all cells" button was above the cell list (instead of below).

Can you consider this suggestion?
Best regards,
Olivier

How to solve this issue?

Stepped graphics takes a lot of time to deal with and those detailes are not very important in some cases.
1. So I want to get those polygons which have multiple points, maybe polygons with points >20 can be selected. Probabily those polygons are what we want.
2. Maybe I can calculate the space between the points of those polygons, if the space of two points are small, for example, 10um, then I can remove those points, so the points can be reduced.
But i am not farmiliar with python in klayout. I have searched a example, but I don't know how to get the point number and points of a polygon. And how to search for the full layout, but this script seems to make function only when I have selected those polygons.

import pya

print('\n\nStarting KLayout Script')
lv = pya.LayoutView.current()
currently_selected_polygons = lv.object_selection # list of ObjectInstPath

if not currently_selected_polygons :
print('no polygons selected in KLayout window')

for o in currently_selected_polygons:
if (o.shape.polygon.is_box()):
bb = o.shape.polygon.bbox()
ll, ur = bb.p1, bb.p2
#points= o.shape.polygon.points()
#points= o.shape.polygon.point_hull()
print(f'{points}' )
#print(f'Selected rect lower left ({ll.x}, {ll.y}) , upper-right ({ur.x}, {ur.y})')
#print(f'{ll.x}')

Could anyone give me some information?

Best regards!
Weiling

In doubt, please use 'contact "at" klayout.org' to reach me.

Matthias

I am using this script you provided to descent into layout hierarchies:

lv = RBA::LayoutView::current
lv || raise("No layout opened")

sel_cv_index = nil
sel_cell = nil
lv.each_object_selected do |sel|
  sel_cv_index = sel.cv_index
  sel.each_inst { |i| sel_cell = i.inst.cell; break }
  break
end

lv.cancel

if sel_cell
  cv = lv.cellview(sel_cv_index)
  cv.cell = sel_cell
  lv.zoom_fit
end

This works nice, but I am also looking for a way to step back "UP" to the parent cell...
Can you help me here?

Thanks,
Martin

May I know how to compile a .py file into a .pyd? I tried using MSYS2, but it only supports Python 3.12, not 3.11, so I wasn’t successful. I believe compiling to .pyd can improve efficiency and help protect the code from accidental modification.
I also tried using the official Python package, and I got a file named cp311-win_amd64.pyd, instead of the more common filename cp311-mingw_x86_64.pyd that I see in the folder.

Good day

"Is is possible to automatically load a layer properties file when a layout 
file is loaded where the layer properties file is located beside the layout 
file and named like the layout file?

For example: if a layout file xyz.gds is loaded and there is a layer 
properties file xyz.lyp in the same directory, it should be loaded 
automatically."

Although there is no explicit option to do so, KLayout can be configured to
achieve this behavior.

To do so, open the Setup dialog, go to "Application", "Layer List". Check the "Use default layer" checkbox and enter the following text into the text box below the checkbox:

$(combine(path(layoutfile),basename(layoutfile))+".lyp")

In that case, the $(..) expression is evaluated and replaced by a path consisting of the layoutfile's directory ("path(x)"), the filename without extension ("basename(x)") and the extension ".lyp". "combine(a,b)" combines the path components using the system specific separator character.

Hence, the layer properties file is derived from the layout file in the desired way. If there is no such file, no specific layer properties file is loaded.

Matthias

Is it possible to make this changes using command line interface ?
If that would be the case what would be the command to do so ?

Best regards
Krzysztof

As a quick mitigation, it is possible to host packages on SourceForge with Subversion selected as the code tool. This will mean manual effort upon releasing GitHub-hosted projects. This used to be very convenient with the subversion bridge.

To facilitate this migration I will add SourceForge to the package repositories and remove GitHub.

Existing packages will be transferred to a read-only KLayout-owned SVN repository so they will continue working.

As a long-term solution, I plan to add Git support for package download. That means:

• It will again be possible to deploy KLayout packages directly from GitHub
• KLayout packages have to reside at the top level of a Git repo (specifically: grain.xml needs to be located at top level). So far, it was possible to use a sub-folder as the package home. This will no longer work. A workaround is to use a Git submodule for the package part.
• This deployment path will only work for new KLayout versions (target is 0.29)

There is a ticket for this: https://github.com/KLayout/klayout/issues/1514

Matthias

Thank you to everyone who works for Klayout. I am a basic user and my question may be simple for many users to answer. When I convert a text into a pcell, it only uses non-Manhattan fonts. The difficulty with the Non-Manhattan font is that it only supports capital characters. Small letters cannot be typed on the mask. Could someone kindly explain how to use different fonts to type capital and small letters on the mask.

Thanks in advance

qrcode_pcell.lym

This PCell macro will provide a new library "QRCodeLib" with a single PCell "QRCode". The latter is able to produce QR code for a given text. It provides some options to adjust the appearance of the QR code.

Enjoy,

Matthias
