Hello, How do I view .def files in klayout and magic? when I try to view it, I get these warnings in both. Also, while viewing gds file in klayout, although it displays all the cells, it uses default technology instead of sky130. How do I fix this? Thanks.

You can use openroad gui to view def/lef files In openroad -gui you can give it as read_lef <lef file> read_def <def file>

Use the circle-T to choose from the installed technologies. You may need to install them. Where to install depends on the OS, I think.

Mine doesn't have an option for sky130. Are these the required files, or is it something else?

Not real sure. Maybe check klayout-> help-> assistant -> technology management

YOu have to install OpenPDK which includes tech files for KLayout. Then you have to pass the path to that files to KLayout. Otherwise KLayout dooes not know where to find them

Hey, I have installed open_pdks but have not set any path specifically for klayout. Can you please tell me which file path does klayout require and how to set it.

In klayout you can go to Tools > Manage Technologies and there import the technology files for klayout in the PDKS: pdk/sky130A/libs.tech/klayout/sky130.lyt

ok, I'll do that, thanks.
