Hi Frank,

EAGLE behaves a little differently than other tool flows if you're used to

having separate schematic and layout editors and with forward and back

annotating.

In EAGLE, always edit either file with the other open.  In this case you

have "constant-annotation".  Anything done in one editor is automatically

reflected in the other.  Its very handy and reduces lots of consistency

problems.  However, if you edit one without the other open then you'll

actually get consistency problems.

To see if this is what you have done, do an ERC in the schematic (with the

PCB open as well).  The last line will tell you if you have a consistency

problem.  If you do, you need to duplicate what you did in the schematic in

the PCB.  Or go back to an older revision and redo with the PCB open.  It

depends on the situation as to what is easier.

If you've done it right, the footprint for the component you added to the

schematic will automatically appear in the PCB.  It may be off in a corner

somewhere so you may want to zoom to fit -- it might just be off the visible

screen.

I hope that helps.

James.

James,

It sounds like you are saying that its a manual process....

For example, if I create a schematic and then the associated board. If I add

a component to the schematic after creating the board (even though the

component may be in a corner somewhere), I need to manually create the

network connections (even though I did so in the schematic already).

Is that correct?

Not so, as long as you have the board file open when you add the

component in the schematic.  THIS IS VERY IMPORTANT !!

If the above is done, you will see the new component footprint when you

view the board. This footprint will be off the board, allowing you to

move it to the position you want. As long as you have the "unrouted"

layer visible, you will see airwires connecting the new component to the

correct places on the existing components. You can then either rout

tracks manually, or ask the autorouter to complete the design for you.

Whenever you work on a design it is IMPERATIVE to have both the board

and the schematic open simultaneously. (For a completely new design,

where you start by drawing the schematic, the board is generated by

clicking on the board symbol in the top tool bar. It is after that step

that you MUST have both files open whenever you are doing any editing)

Thanks for your feedback, I will make sure to keep both my schematic and

board views open at all times.

And as a helpful hint that you should do this, Eagle will always open

both if they both exist. So if you open "myProject.sch" and there is a

"myProject.brd" in the same directory, the board editor will be opened

automatically (but minimised).

True.  The catch comes if you then close one of them, because the other

will stay open, and you can make a change without both being open.

If you close one file, it is safest to close both so you are not tempted

to make changes on one file only.

John G.

When closing a file, I'd prefer that EAGLE automatically close the

"other" file, or at least, ask the user if he wants to close the "other"

file.

If you use the control panel to open and close projects (green button)

then they are both closed or opened.

Use the exit function to close all of eagle's windows.
