silly question ?

Hi Guys

This may sound like a silly question but,

How do I produce a BOM, I found bom.ulp but nothing in the book or help

files.

I'm using ver 5.3 at the moment

 

many thanks

Select the ULP icon from the toolbar and then run the BOM ulp.

Hello Richard,

There is also a part2html.ulp so you can paste the BOM into excel.  Run this

ulp from the Board.

Mike

There is little built into Eagle to make a BOM for you.  There are various

ULPs that either make little more than a primitive parts list, rely on a

external database, or use the user definable attributes available in Eagle

5.  Then there are a lot of details about how to know when one device in a

schematic is really a different part from another, how to deal with devices

that don't belong on the BOM at all, seeding other spreadsheet information,

etc.  It gets complicated fast when you really think thru the details.  For

example, two LEDs might have the different values "Power" and "Status" but

are the same physical part and should be on the same BOM line.  On the

other hand, the value field can be the sole way to distinguish a 10K

resistor from a 1K resistor.

You might want to take a look at my BOM ULP.  It uses a bunch of attributes

that can be defaulted in the library and overridden in the schematic as

required.  The BOM ULP actually exports a fairly dumb parts list to a file,

then runs a external program that determines the common parts, computes

quantities, seeds cells with formulas for computing board cost, and writes

the result to a tab delimited file for importing into a spreadsheet.  It

even copies a template spreadsheet to the directory for that board.  This

has the formatting of the various columns already set so everything looks

right when importing the tabbed file.  All this stuff is included in my

Eagle Tools release at http://www.embedinc.com/pic/dload.htm.  The doc file

for program CSV_BOM describes the overall process of creating a BOM.  The

various attributes are described in the EAGLE_ATTR doc file.
