Phantom Devices

I am new to Eagle and new to this newsgroup. I have created a schematic

with a part that I created and that seems to be well. But somehow in

the creation of the part and adding it to the schematic, I added two

devices that show up on the board as U$2 and U$3. The schematic has

the real one, U$1, and it is on the board as it should be. But I

cannot seem to get rid of U$2 and U$3. Trying to delete them in the

board gets a me an error message saying to delete in the schematic.

I cannot see it in the schematic, so I cannot delete it there. I

tried a command line delete for U$2, and it says it is not found.

What else should I try? -Chuck-

    It's very possible that you have created them on top of each other. To

    see if that is true, look at a single wire going into a pin.  If

    there's a dot on that, then you have multiple parts. 

     

    Also try to put the board to extents and see if it's off somewhere.

    Also try a find... or a show... might help.

    Thanks, but even if I delete U$1 from the Schematic, U$2 and U$3 still

    show on the board, but not on the schematic.

     

    Using some examples from the ULP manual, I wrote some code to dump the

    schematic objects. The output is long, but this is what it shows for

    the parts in question. It looks like the bad parts are not associated

    with a sheet. -Chuck-

     

     

    Part: R16          R16 used on sheet 1

     

    Part: U$1          U$1 used on sheet 1

     

    Part: U$2

    Part: U$3

    Part: X1          X1-1 used on sheet 1

         X1-2 used on sheet 1

    Shooting in the dark but is seems like you changed a component or device

    in a lib or the path to a lib and have a broken device in your sch or brd.

     

    Have you used the info on the board for the U$2 U$3 and U$1.

     

    Make a copy of the sch file (new name) without the brd and then make the

    board from the sch. Do they show up on the new board?

     

    Duplicate both sch and brd. Edit only the board and delete the two

    parts. Open the sch and check if you are consistent.

    Thanks. I finally got rid of them but it was strange.

     

    Not sure about your first question. I used U$2, but I have never been

    able to use U$2 and U$3.

     

    I did this and they did show up on the new board.

     

    I was able to duplicate both sch and brd, and by closing the sch, I was

    able to delete the bad ones, but then when I opened the sch it told me I

      was inconsistent.

     

    But after deleting the good part off of the sch (which removed the good

    U$1 as expected) I noticed that when I added it back, it linked to U$2

    on the board and all the proper airwires were there (U$2 and U$3 only

    had power and ground airwires before). So I deleted it off of the sch

    and that deleted U$2 off the board! I repeated that again to get rid of

    U$3, then I added the part a final time to the sch which created U$1

    again. I placed it and routed it and now I am rid of the bad devices.

    Finally! -Chuck-
