Hello friends, I see some people are using klayout for physical implementation in their projects. It is awesome, I thought this tool was only a gds viewer. I can not find a good tutorial to get started. Can someone that has used klayout for analog design point to some good reference?

Even if klayout has a beautiful interface. I think at this moment in time magic is the better choice. In magic you have online DRC, you can do LVS and have pcells. I fear Klayout is lacking behind in all of this.
