error message when replacing parts

Yes, this is a really annoying problem. I usually have to delete the .brd file from the project and then allow the schematic to create a new board. Problem being that I lose time, especially if I have got the layout close to completion.

 

That's a bit overkill David,

What's happening is that EAGLE replaces the component but doesn't

reconnect the nets. Running the ERC will tell you where the consistency

issues arise so that you can correct them manually, and that's a lot

less work then starting the layout over generally.

In some cases just moving the component and putting it back on the net

connections takes care of the problem. Other times you can just add

junction dots where the nets meet the part.

When I did the replace, I found that the part, in this case, a polarized cap, was no longer connected.  Moving it away, then back reconnected it, but running electrical check again still shows same consistency errors.  "Different connections on C24 pin + and pad + (none / N$91)" and "Different connections on C24 pin - and pad - (none / AGND)  What does this mean?  Thanks.

 

Hi Rick,

Use the show command and click on the nets and make sure the pins light

up, if they do then there should still be a connection.

The alternative now would be to delete the offending signals on the

board until consistency is restored, then hook everything up again. For

the time being it may be better to avoid the replace command and simply

delete and add the part again.

It seems that if I do a replace of a part that was originally from a different library it updates only the part being replaced.  If I replace a part with the same part from the same library, it updates all the parts by the same name in the schematic.  This seems to be when the error occurs, but it only occurs sometimes.  Also, to my surprise, when I update the part in the schematic, the corresponding part in the PCB is not updated to the latest in the library.  Is it supposed to work this way?

 

Hi Rick,

If the board and schematic are consistent then they both update, but if

consistency is broken then they won't. Since the update bug causes a

break in consistency this is a natural consequence.

It's being worked on as we speak.
