Two years ago, when I was working for a different company, I used the =
PADs PCB package from (now) Mentor Graphics. It is a very expensive =
product, and beyond the needs of my present company. These days I use =
Eagle, which I am actually quite pleased with.

Sometimes the Schematic and the PCB get out of synch - IC4 is one thing =
in the Schematic and something else on the PCB.
In any case, the last PADs revision I worked with had a really neat =
feature - it would generate a differences list between the Schematic =
data base and the PCB layout data base.  It would analyze the data base =
and display, in side-by-side form, all the differences between the =
Schematic & the PCB.  You could then do an edit for each instance =
(object/item) to make the PCB agree with the Schematic, or to make the =
Schematic agree with the PCB. When you were done there would be only one =
design data base with (hopefully) the proper entries for everything, =
thus generating a BOM produced correct & consistent results.

Does anyone know of anything similar for Eagle?
