This is my first time using th autorouter, and I'm struggling with clearance violations. After some work the board passes DRC, but when I attempt to autoroute/setup, I get a huge number of errors of the form:
Error : Pad U14-1 Appears to be unroutable. Violation against Rule - Clearance Clearance Constraint (Gap=7mil) (All),(All) Detected.
When I examine that part/pin using either the Distance or the Between Primitives tools I see a clearance of 13.78 mils between pins. Nothing else is anywhere near the pin.
Can someone either tell me what I'm doing wrong, or where I can find a report or other data that would provide additional information to help me figure it out?
thanks,
