Hello,
I've a novice user of EAGLE CAD and I've come across some troubling behavior.
I am getting false ERC passing on the consistency check between the schematic and the board. I have no physical lines either on top or bottom running on the board at all, and when I run ERC, EAGLE reports back that the schematic and board are consistent. Nope! They aren't, I have no traces on my board, EAGLE. I wanted to make sure I'm not crazy, so first I made 100% sure:
-- I've routed nets to the MIDDLE of the green pin on all parts ( they are )
-- The green wire are NET wires and not LINES. They are present on the NET layer. ( yes, they are )
-- The green NET wire & the red symbol lines intersent at 1 point inside the green circle representing the pins ( they do )
-- I've checked 3x that the symbols and net lines are on-grid 0.1", as well as the pins ( they are )
-- I've tried moving the schematic symbols once routed to make sure the rubber-band behavior of nets/symbols is present in the schematic for all parts ( it is )
-- I get the proper flight lines / rats nets lines when the new board is created, and they match the schematic ( they do )
Still, ERC reports back that the board / schematic are consistent in the case of totally missing top/bottom traces on the board.
NOW, the interesting part:
-- When I route a net wire through the green pin, so that the wire extends more than halfway through the green pin, THEN, running ERC, EAGLE reports back that the net is actually open and that the trace is missing from the board. Look closely on the G pin as opposed to the first picture:
What am I doing wrong here? In the first picture I am clearly inside the boundary of the G pin, the flight lines exist on the board, the symbol and wires on it are rubber banded, but ERC reports no errors for unconnected traces.
In the second picture, ERC correctly reports an open circuit on the board.
??? Stumped ???
