In this case, I wasn't talking about the BOM, I was talking about
the Family Definition drawings. I haven't written any of those yet for
Traversal, so I can't send you an example. But what it does is control the
relationship between a family of company stock numbers and the corresponding
manufacturers' part number formats. There's other stuff in the document,
but that's the main function.
For example, if we say that common 5% chip resistors will have stock
numbers starting with a root number of RCB followed by fields for body size,
power rating, and value, there would be a family definition document with
drawing number A-FD-RCB. It would specify the stock number structure and
coding, and state the format rules for generating the corresponding part
numbers for Panasonic, TDK, Dale, Rohm, KOA, and everybody else on the
approved manufacturer list, along with stock numbers for big distributors
like Digi-Key and Mouser. So, for instance, the company stock number for an
0603 1/16W 1.6K resistor might be something like RCB06-16-162J.
Now, as to BOMs, that's worth discussing too. I've never heard of
csv format, but most schematic entry programs can generate a BOM as a
tab-separated text file. You can do pretty much anything with that. Some
people like to read it into a spreadsheet program and format it that way.
Blaah. But a decent word processor like OOo Writer is a good way to plug
the parts list into a clean-looking table, inside a document template with
title blocks and places to sign off. If somebody can find the time, it
should be possible to write a shell script to automate the task, since
OpenDoc is a plain-text standard and can be manipulated by Unix utilities.
