Ratsnest doesn't look for better ways to interconnect things but it does help you when you are placing your components as you can see where areas of airwire congestion are and arrange components so things flow more cleanly and the airwires run in more obvious places. Anything that isn't GND will be isolated from it.
Whenever a via/pad/signal named GND comes into contact with the polygon it will make a connection to it. For example you could draw a polygon around an entire layer, name it GND and it will become your GND plane. Polygons are shapes drawn on a layer, usually a signal layer, which are used for creating areas of copper. Their purpose is to show you by the most direct path what connects to what, but they aren't physical connections, just an indication of where signals go. I would also like to know if this tool looks for a better way to interconnect the electronics devices on the board designing?Īirwires are the yellow lines which criss cross all over your board when you haven't got all your routes finished. Sincerely, i don't know what airwires means in this case, neither polygones. I have looked for it on internet and it says that it calculates the shortest possible airwires and polygones. Hi, this post could be a trivial issue, but i want to know what it is ratsnest and what is it for?
