Consistency errors

Hi Jim,

Did you edit the schematic or board without the corresponding file open?

This is a guaranteed way to create consistency errors. The missing air

wires would probably be because the net was added in the schematic while

back annotation wasn't working so the board knows nothing about the net.

You've not really given enough information about what the errors actually

are for us to be able to help, can you post up what the actual messages are

saying?

Basically what you'll need to do is back out any additions to the schematic

that happened while not in sync and make sure any property changes are in

sync across both the schematic and the board. Keep running ERC and working

through the list of differences until you see all the errors are cleared.

If you can supply more info then we can probably help more.

Best Regards,

Rachael

I now have the following errors:

Different connections on U15P pin V- and pad 4 (-12V/$$1)    2

Different connections on U17P pin V- and pad 4 (-12V/$$1)    3

Different connections on U20P pin V- and pad 4 (-12V/$$1)    3

Part R46 has different values in schematic and board (2.61k Ohms/2.61K)

Part R48 has different values in schematic and board (2.2k Ohms/2.2K)

Part R84 has different values in schematic and board (2.2k Ohms/2.2K)

what should I try now?

So I don't think you've done it right. What the first 5 errors are saying

is that on the schematic the pins of those parts listed are connected  to

-12V whereas on the board they are not connected to that net. There may be

a different named net on those pads in the board, I can't tell. So you need

to totally remove the nets in the schematic that connect to those 5 pins.

In the board you need to go find the pads and make sure there are no nets

connecting to them either. If you do that these errors WILL go away. They

are still there because you still have mismatching things connected to

the,

The new 3 errors is because you have added values in the schematic and in

the board separately and you have a difference in the case i.e. k vs K.

In fact, you also have Ohms in one and not in the other. Both need to be

EXACTLY the same.

Hello Jim,

I hope you're doing well. If you can send me the files for review and

I'll correct them if you wish. In this case you would have to delete the

nets on both the schematic and the board to get them back to a normal state.

Here's how you could make sure you are not burying yourself deeper into

a hole. In the schematic delete the -12V net from R48 pin 2. Now go to

the board and delete the $$1 trace from pad two of resistor R48. Now run

the ERC. You should have 1 less error. Rinse and repeat to get of the rest.

The different values error can be corrected by running the

make-value-consistent.ulp in the editor that contains the values you

want on both the schematic and the board.

Remember to constantly run the ERC to make sure you are making progress

and not going backwards.

Jorge Garcia

I deleted the source on the schematic as directed then went to the board and deleted the trace. Consistency  error is still there and now I have a warning about unconnected pin on R48.

I reconnected the -12V source to R48 and reconnected the trace on the board. Warning is gone error remains.

Hi Jim,

The warning was fine and to be expected as you had deliberately

disconnected the pin.

Was the error message exactly the same after you deleted the net?

I suspect there was some net remaining connected to the pin which retained

the net name. You need to remove the net that connects directly to the pins

in the schematic. If you do this correctly the errors WILL go away.

As Jorge says, it's often safer to try one at a time, running ERC after

every change. With the limited number and type of errors you had I wasn't

worried about things being made worse by doing it all at once but as a

matter of good practice Jorge is right on that front so do the changes one

at a time, running ERC after every change to verify.

If you are still having issues then please include screen shots of the

sections of the schematic / board so we can see what's going on as well as

the exact wording of the very latest messages.

Best Regards,

Rachael

I managed to get two of the errors cleared. R48 and R84 both were completely isolated and the error went away. As soon as I tried to reconnect the two parts the errors came back.  I gave up and went home for the night. I tried again this afternoon and connected both parts. One of the parts has no error, but now I get a warning that one of the pads, on each parts I have connected, is not connected, even though I have now connected both pads on both parts.

I still have problems with the other three pins. If I try to delete any part of the -12V node, I loose the entire node for almost half the board. Reconnecting to U15.4 doesn't seem to be recognized by eagle at all.

I have other projects that I need to work on the rest of the week, I will try again next week and see if I have any luck then.
