Board inconsistency -how to update?

Is there a way to "synchronize" the board file with the current schematic?

They are automatically kept in synch as long as you have both open

whenever you make a change. Eagle defaults to always opening both (or at

least offers to, you can sometimes say no).

Yes, I know, but they have come out of sync. Probably because I disabled

the board file (renamed its extension to ._RD) when I should have made a

backup copy instead, replaced parts etc.

Basically, I don't want to lose the board layout I have in that file,

but want to update it to be consistent with the schematic. Is there a

way to force a synchronization between the two?

HI,

if you run "ERC" so you get a list of the diffs between board

an schematic.

Then you can do the changes by hand. If you have done all

errors the "ERC" make flags the board and schematic as sync.

Yes, I do get several errors when pressing "ERC" in the schematic, such

as consistency errors: "Part xx not found in board" and warnings: "Only

one pin on net xx".

So I go to the board, add the first missing component and naming it the

same as in the schematic. I was hoping to see the wires magically appear

but not so. And in the schematic I still get the same errors.

How should I proceed?

Hi,

the Warning with one pin is in the schematic.

Look at the Net "Show netname".

If you see that the net is highighted and the pins not, move the symbol

a little bit away and back to the Net. It will be connect to the symbol.

(If not check Grid etc.)

The wires will be "magically appear" in the board if you use "export

Netscript"(Help Netscript would be your friend). Then run the exported

script in the  board....

You need to do this manually. You need to understand how eagle handles

this. Note that when consistancy is broken, NO changes on either brd or

sch is reflected on the other.

-First, make sure all the devices are present at both schematic and

board. Also make sure they have the same name (you can rename either on

sch or brd to match)

-2nd, for brd and sch, make sure the connections are the same between

devices, and that they have same name. You can easily add and remove

wires on sch, and on brd you need to use "delete" or "signal" (not

wire!) to erase and add connections. Use "name" to rename on both sides.

Do ERC now and then to check how its going. You will regain consistancy

after ERC if no consistancy errors are found.

Of course, if you have a very long list of consistancy errors, this may

add up to some amount of work.
