I've 3 boards each with it's own schematic but with a lot of common components. I want to generate an unique BOM for all this boards to know quantity of each piece I need and make a single order BOM.
For example: I can extract a single BOM with run bom.ulp
But now I want to merge this BOMs in a single file with quantities of a common single piece sum togheder.
There is a method in EAGLE or Excel to do this? I want avoid to manually do this becouse of risk to make errors in count or add pieces.
