Hi, @User what is exactly the 'ratsnets' command you expect supposed to do ? i think i can implement it easily, if i know exactly how to present a 'connectivity view' i can do that. The problem in such big schematics is a full view doesn't tell anything, may be should i zoom in sequence to all gates a net goes into or comes from? what i used to do is to 'highlight a net' (select a label and press 'k') then you can make the schematic invisible, viewing only the highlight (press '5' key, press again to get back schematic view), this tells you all points a net goes. However some more efficient method could be implemented.
