usage.
Table 5-4. Table of BOM Processing Files
File Usage
bn_bomprocess.log
Output file from
bn_bomprocess
, including when run via
mechbom
or
xcelbom
.
project
_avl_update
Output file. A list of parts (number, description, plant code) that need to have AVLs
assigned in other plants
project
_bne_bp.lst
Output. Your schematic should produce this file when Viewlogic’s Part Lister is run
from the
bn_bomprocess
. It contains two blank fields, a part number, schematic
symbol name, package type, value, quantity, and list of ref descriptors (
mechbom
generates an empty file).
project
.cfg
Input file. This configuration file replaces a myriad of options on the command line for
bn_bomprocess
and lets you specify such information as: input/output files and
directories, server, BOM type, part extraction from schematic, etc.
The
mechbom
utility creates its own config file by adding a few project-specific lines
to a template.
project
_changes.rev
Output. New revision file containing extensive data on all the changes, including
design identification, revs, target plant, part numbers, description, and revisions for
parts, etc.
project
_cost.lst
Output. A list of part cost information: part number, description, quantity, unit cost
(per part), full cost (for the project).
project
_depoped.lst
Input. A list of part numbers and quantities to remove from a BOM
project
_leadtime.lst
Output file. Contains, for every part: number, description, quantity, and lead time, i.e.,
how many weeks
project
.lst
Input file. Also known as an
include file
, this file may initially be created by EDA
personnel from email you send containing information generated by
partmgr
.
May be created by
build_lst
from
project
.saplis
file, for input to
mechbom
and
subsequent input to
bn_bomprocess
.
One or more of these files may be specified in the config file. Each line contains a
part number, quantity, and class code.
project
_parts.lst
Output file. This lists all the parts; for each: number, revision, description, total
number in design, and ref designators.
