I am designing a board layout in Eagle. Before manual/auto routing, I made a polygon around the corners and named it as GND. Then I used the autorouter for routing. After the routing is complete, there are few yellow wires left and these wires are of GND connections.
As you can see in the image, there is a yellow wire attached to the GND of the
LED1 and the 3rd pin of the
JP2. According to my understanding, this should not happen because I have made the Polygon of GND. What could be the problem. Am I doing something wrong. Please help. Thanks.!
