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
