Can anyone tell me why my klayout is not opening in default mode, also I want to load it with sky130pdk how can I do it ?, when I was trying to add sky130 layer porperties it is showing the following error how to resolve it ?

Hi @Sudeep Gopavaram, I believe the error message says that you need to open a layout before loading the layer properties. On a sidenote, you can now install the sky130 package from Efabless directly via KLayout's package manager. You can try this out under "Tools -> Manage Packages" if you like:

@Sudeep Gopavaram Is there a

Preferences

option in the file menu? If there is you might be able to set

open in edit mode

as the default. You also might be able to set a default layer file there. If you’re starting klayout from the command line, try using the

-e

option for edit mode and

-nn <layer_file.lyt>

option to set the layer file.
