Does anyone know how to access #C016UL7AQ73 pdks in klayout? I have configured it, but can't access the library in the editor option.

Hi @Abhay Kulkarni have you updated gdsfactory to the latest version as we discussed?

Hi Leo. Yes I did actually. I went here and installed complete gdsfactory mentioned there by putting in terminal this: "pip install "gdsfactory[full]" --upgrade"

Alright, can you tell me which gdsfactory version you have installed now? This should be the latest version:

$ pip3 show gdsfactory
Name: gdsfactory
Version: 8.15.0

command: pip3 show gdsfactory Name: gdsfactory Version: 8.15.0 Summary: python library to generate GDS layouts Home-page: Author: Author-email: gdsfactory community <contact@gdsfactory.com> License: Location: /home/abhay/.local/lib/python3.10/site-packages Requires: attrs, freetype-py, ipykernel, jinja2, kfactory, loguru, mapbox_earcut, matplotlib, networkx, numpy, orjson, pandas, pydantic, pydantic-extra-types, pydantic-settings, pyyaml, qrcode, rectpack, rich, scikit-image, scipy, shapely, toolz, trimesh, typer, types-PyYAML, watchdog Required-by: gplugins

I'm a bit at a loss here, the versions match up and it should just work... If you start a Python, are you able to import kfactory? What is the path to it?

$ python3
Python 3.12.6 (main, Sep  7 2024, 14:20:15) [GCC 14.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import kfactory
>>> print(kfactory.__file__)
/home/leo/.local/lib/python3.12/site-packages/kfactory/__init__.py

oh it says, No Module named kfactory. So looks like it has not got installed or configured.

Okay, that is a starting point. What version of Python are you using?

I had python 3.8.10 . But then I installed python3.10 also seperately which for some reason doesn't show when i do 'python3 -V'

might be that you have the libraries installed but only for the other version of python. If you want to make sure you install something for a specific python version run

python3.10 -m pip install ...

Output of that : Traceback (most recent call last): File "/usr/lib/python3.10/runpy.py", line 196, in _run_module_as_main return _run_code(code, main_globals, None, File "/usr/lib/python3.10/runpy.py", line 86, in _run_code exec(code, run_globals) File "/usr/lib/python3/dist-packages/pip/__main__.py", line 19, in <module> sys.exit(_main()) File "/usr/lib/python3/dist-packages/pip/_internal/cli/main.py", line 73, in main command = create_command(cmd_name, isolated=("--isolated" in cmd_args)) File "/usr/lib/python3/dist-packages/pip/_internal/commands/__init__.py", line 96, in create_command module = importlib.import_module(module_path) File "/usr/lib/python3.10/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1050, in _gcd_import File "<frozen importlib._bootstrap>", line 1027, in _find_and_load File "<frozen importlib._bootstrap>", line 1006, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 688, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 883, in exec_module File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed File "/usr/lib/python3/dist-packages/pip/_internal/commands/install.py", line 24, in <module> from pip._internal.cli.req_command import RequirementCommand File "/usr/lib/python3/dist-packages/pip/_internal/cli/req_command.py", line 15, in <module> from pip._internal.index.package_finder import PackageFinder File "/usr/lib/python3/dist-packages/pip/_internal/index/package_finder.py", line 21, in <module> from pip._internal.index.collector import parse_links File "/usr/lib/python3/dist-packages/pip/_internal/index/collector.py", line 12, in <module> from pip._vendor import html5lib, requests ImportError: cannot import name 'html5lib' from 'pip._vendor' (/usr/lib/python3/dist-packages/pip/_vendor/__init__.py)

A different way to run KLayout with gdsfactory is by using Nix. Efabless has the nix-eda repository with a collection of tools. https://github.com/efabless/nix-eda You simply need to install Nix (you can follow the OpenLane 2 documentation: https://openlane2.readthedocs.io/en/latest/getting_started/common/nix_installation/index.html) and after that you can run:

nix run github:efabless/nix-eda#klayout-gdsfactory

to open KLayout with gdsfactory installed. Maybe this works for you.

Thanks a lot dude !! I will try it out and let you know.

That's great to hear! 😃 I don't quite get your second point. Are you missing any transistor types? Using the

type

parameter you can select a different one. If you have any issues with the PCells, please open an issue here: https://github.com/efabless/sky130_klayout_pdk Cheers!

Hi !! Yes, I think I missed the drop down menu ! 😄 . I am good to go now! thanks for your support and best wishes. Keep in touch for any more discussions !
