A few operations get performed fairly regularly when editing PyPPM source files. To streamline the process as much as possible, I wrote a few support scripts.
Here's a quick rundown of the support scripts, and what they do.
The board script converts all schematic files in the current working
directory into a new empty printed circuit board design file set. This should
only be run when creating a new board, because it completely destroys any
existing board designs in the current directory.
The bom script takes bill-of-materials CSV files and outputs a list of all
unique part numbers and their occurrence count. This is useful when ordering
parts for a design from Digi-Key, because any given part number may occur more
than once in different schematic sections.
The bom-internal script takes bill-of-materials information embedded in the
schematics of the current directory to generate long (per schematic page) and
short (summarized) bill of materials CSV files. For this script to work, every
schematic part needs to have a partno attribute that corresponds to its
bill of materials line item identifier.
The build script runs any simulations in the current working directory,
generating any plot files that can be made. This is one of the uglier, less
flexible hacks in the scripts directory. You've been warned.
The clean script undoes the results of the build script.
The edit script is used to rapidly open either the schematics or the printed
circuit board of a given hardware design. It also simplifies the process of
purging temporary scratch files and making gerbers and postscripts.
The effbw (Octave) script is used to compute effective bandwidth when given
a text file containing frequencies in column one and gains in column two.
The layer.awk script a small script used by scripts in the designs
directory to locate the boundaries of a given layer in a PCB source file.
The print script prints all schematics in the current working directory.
