Hi, I'm new in using klayout for drawing layouts. I've tried to open pre-built design in skywater lib.refs and has also performed the DRC by clicking "Run klayout DRC" as shown in the first picture. After clicking the button, a window popped up showing some kind of DRC process (I guess). At the end of the process, it showed me the "Marker Database Browser" with no explanation (you may refer to the second picture). My question is: Did I perform the DRC correctly? If didn't, what is the correct way of doing the DRC? Thanks.
