Consistency errors

Well, its happened again. I have consistency errors. How do I resolve them. I have tried to delete the offending part from the schematic, both with the board open and closed. I have tried replacing the offending part with a new part from a brand new library. I have tried to delete the part from the schematic, close the schematic reopen the schematic and the board. I have airwires on the board but can't place or select the part. What do I try next?

Hi Jim,

I hope you're doing well. Remember to always have the board and

schematic open at the same time together. That will avoid running into

consistency issues.

Remember to run the ERC often as you make changes to make sure you are

going the right direction. When you are trying to get back consistency

you need both the schematic and the board to be open at the same time.

How many errors do you have now? If the error is part is found in one

editor but not the other. Then the easiest thing to do is to remove the

part from the editor that has it.

Remember that ALL of the consistency errors must be resolved before you

can regain consistency and continue working.

I currently have 3 errors and two warnings, all on the schematic.

The errors are "Different connections on Pins" on two different parts.

The warnings are "Only one pin on net" for two different nets.

What do I do to correct these errors, and will this get me back consistency?

Change the schematic so the connections in the schematic match the connections in the board. Make the changes one at a time and run ERC after each change to see if the error has gone away. If it hasn't gone away then the change wasn't right. Once you have made all the changes and got back consistency, you can make the changes in the schematic again to get it to how you really want it to be but remember NEVER EVER edit the schematic or board without the other one being open.

Best Regards,

Rachael

I can't make the connections match between the two. Among the many problems I have is:

1. one of the parts on the schematic won't connect to wires drawn on the schematic unless I press the ALT button.

2. In trying to resolve Drill Distance errors, which got this mess started, I created a new library for the original part, new symbol, new package, new device. In doing this, the schematic was closed as was the board. Upon reopening the schematic and updating the library, I got the consistency error. Now, if I add the missing part to the board it is entered as E$1, the schematic is showing U$1. I cannot change this lable, I cannot move this part, I cannot check info on the part, I cannot select this part in anyway except via the command line. This also means that I cannot make connections to a part that is no longer recognized by eagle board editor.

3. I had already completed routing the entire board, and was in the process of resolving 4 drill dimension errors and 16 overlap errors on this same part. Thats why I recreated the library. The new library had 16 clearence errors that I think I have corrected, but can't check because I have consistency errors.

Should I just delete the board and lose 1 months worth of work or does anyone have any other ideas?

Do the nets in the schematic have different net names to those in the board?

Have you updated the part in both the schematic and the board with the new library part?

No you shouldn't delete the board. 3 errors (ignore the warnings they are not important at this point) is nothing and absolutely no reason to delete the board and lose a month of work.

Sounds like your schematic and/or lib part was drawn off 0.1inch grid.

This is not recommended, cause schematic doesnt catch pins, like a pcb

does with pads. But I dont understand how that could have happened.

You can rename E$1 and U$1 to the same new name and you are one step

closer to consistancy. You need to practice a couple of new functions

that you normally dont do on board, when consistant. That is the name

and net functions. Net connects pads with airwires, and it needs to be

connected as on schematics. Also name the airwire to the same netname as

in schematics. Do ERC after every change to see how it went.

When this is said, I myself found a lost consistancy a few days ago

(with 7.6.2 bet), so I know there are some rare bugs left. But since I

was unable to focus on repeating it, I just fixed it and let it pass for

this time.

No! Thats a waste of time. Use this event to learn how to regain

consistancy. Once you know howto, its not that hard.

PS:

Eagle always keeps the last 10 backups, named .s#1 for the last, .s#2

for 2nd gen and so on. For boards, the name is .b#1,... You can try

recovering you data there. Check their creation date and rename the

chosen ones to .sch and .brd (may be worth backing up the bad files).

I couldn't rename the part since I couldn't select the part.

I have since deleted the board, since it is faster to rebuild that to correct. I still have the original problem. The part that kept giving me errors that I could correct, is still wrong and noone knows why.

Deleting the board was totally the wrong thing to do. I suspect most of us who have commented on this could have fixed your issues in a matter of minutes if we had access to the sch/brd and the lbr containing your problematic part. The problem is either we are not getting the full story or you aren't doing exactly as people have suggested.

If you still have the original files and didn't just delete your only copy I suggest you either post them up so people can have a look or send the to Jorge Garcia at cadsoft (support@cadsoftusa.com).

Hi Rachael,

I think that deleting the board is sometimes the fastest way to rebuild

it correctly,

especially if someone says he doesn't know how to delete a board.

Look at this thread and the help you and others have  provided,

long  discussions which lead to nothing.

I have the impression that the poster did not do what you suggested so

no positive result.

The poster should have placed the files here and I bet the users here

would have helped immediately.

I fear frustration and desperation have taken over and Jim is now battling these as well as inexperience with EAGLE. I can understand this, sometimes when you get totally bogged down in an issue you just get to a point where, no matter what, you just can't see the solution that is staring you in the face.

He has posted links to his .lbr files on another thread although they are on some strange hosting site that looks slightly like the type of site that also hosts adware and other crap so I am not downloading anything from there. He should post the .lbr file so we can get it straight from here (Jim: If you go to the advanced editor on here (Element 14) there is an attach button). As it's a commercial project I can understand why he wouldn't post the actual design files up.

Best Regards,

Rachael
