Does anyone knows if the open-source IC tools (mainly ngspice, xschem, magic, klayout, netgen) are able to run on a CentOS/RockyLinux enviroment ? It would be good to have both the closed tools and open tools on the same local computer without the usage of VM's or anything related... This is just a question if anyone have tried that, probably I'm going to try this at some time. (editado)

Yes. Before switching to Ubuntu our Docker image (IIC-OSIC-TOOLS) was built on RockyLinux.

Good to know! Any particular issue occurred to make the change? (rocky to Ubuntu)

Not really, finding the correct packages to install was the hard part.
