Making Hardware with KiCad and Friends
KiCad is a well-established Open Source EDA suite that provides tools
for most of the basic tasks in circuit design. In larger projects,
and especially those of an open and collaborative nature, additional
requirements appear that KiCad can only partially satisfy.
Specifically, collaborative projects benefit from visualization that
helps to quickly follow the work of others and to track a project's
revision history. Furthermore, an automated and thus easily
reproducible workflow lowers the barrier of entry and avoids costly
mistakes.
In the Qi-Hardware project, we use KiCad as the centerpiece for various
hardware designs and enhance its functionality with patches or external
programs. This presentation will describe the complete workflow from
design to fabrication, introduce the various tools we use to complement
KiCad, and also briefly address common design rules.

Werner got hooked on Linux in the days of the 0.12 kernel and started
to get his hands dirty from early on with contributions like the LILO
boot loader, the initial RAM disk (initrd), and the MS-DOS file system.
Later activities led him into networking, with the Linux-ATM project as
part of his PhD thesis, and he eventually landed in the Openmoko project.
Having had a taste of hardware there, but eager to do more, he then
journeyed deeper into the world of electronics and finally joined the
Qi-Hardware project, where he now dabbles with making gadgets that aim
to blend software and hardware under common principles of freedom.

KiCad:
\begin{itemize}
\item Project file: {\tt {\em project}.pro}
\item Schematics: {\tt {\em project}.sch}, {\tt {\em subsheet}.sch}
\item Footprint mapping: {\tt {\em project}.cmp}
\item Layout: {\tt {\em project}.brd}

\item Bookshelf (for dsv)
\item Project-local libraries
\end{itemize}
\end{frame}
% --- What doesn't ------------------------------------------------------------
\begin{frame}{What doesn't}
KiCad:
\begin{itemize}
\item Netlist: {\tt {\em project}.net} \\
Generate with eeschema from {\tt *.sch} and {\tt {\em project}.cmp}
\item Caches and backups: {\tt {\em project}.bak}, {\tt {\em project}.000},
{\tt {\em project}-cache.lib}
\item Postscript: {\tt {\em project}-{\em layer}.g{\em XX}}
\item Gerbers: {\tt {\em project}-{\em layer}.g{\em XX}}
\item BOMs: {\tt {\em project}.lst}, {\tt {\em project}.cvs}

% --- Project File ------------------------------------------------------------
\begin{frame}{Project File}
Project settings. Lists of libraries.
Issues:
\begin{itemize}
\item Local absolute paths
\item Default libraries
\item Timestamps $\rightarrow$ commit noise
\end{itemize}
Solution:

\end{frame}
% --- Makefile ----------------------------------------------------------------
\begin{frame}[fragile]{Makefile}
Issues:
\begin{itemize}
\item Shortcuts
\item Glue tools together
\item Avoid mistakes
\item Share common procedures
\end{itemize}
Example:

pcbnew --plot=ps --plot-fill-all-zones --layers=Front \
--plot-mirror $(PROJECT).brd

\begin{itemize}
\item Idea: command-line access to main output functions
\item eeschema
\begin{itemize}
\item Visualization: Postscript (and SVG, DXF)
\item BOM $\rightarrow$ BOOM
\item Netlist, ERC
\end{itemize}
\item pcbnew
\begin{itemize}
\item Fabrication: Gerbers, drill (Excellon), component positions
\item Visualization and DIY: Postscript
\item Attributes: mirror, size, origin, fill zones, $\ldots$

% --- Data Sheet Viewer (dsv) -------------------------------------------------
\begin{frame}[fragile]{Data Sheet Viewer (dsv)}
\begin{itemize}
\item Bookshelf: name and aliases $rightarrow$ PDF or ZIP with PDF
\item Download (wget) to local cache
\item Hierarchical lookup by name or alias
\item Example: \\
{\tt dsv avr} $\rightarrow$ ATtiny87 ({\tt doc8265.pdf})
$\rightarrow$ xpdf
\end{itemize}
Bookshelf example:
\begin{verbatim}
N: attiny87
A: attiny167
A: avr
D: http://www.atmel.com/Images/doc8265.pdf
\end{verbatim}
\end{frame}
% --- Data Sheet Viewer (dsv) -------------------------------------------------
\begin{frame}{dsv Motivation}
\begin{itemize}
\item Make sure everybody uses the same data sheet
\begin{itemize}
\item Same component
\item Same manufacturer
\item Same data sheet revision
\end{itemize}
\item Copyright: can't just check in PDF
\item Industrial pragmatism: mail or ``internal'' repository
\item Qi-Hardware: send {\tt BOOKSHELF} around
\end{itemize}
\url{eda-tools/dsv}
\end{frame}
% --- Schematics Symbol Catalog ----------------------------------------------

How it works:
\begin{itemize}
\item Walk git revision history
\item Check out project whenever schematics change
\item Run eeschema to make Postscript
\item Convert to PNG (find diffs, with highlighting) and PDF
\item Wrap in HTML
\end{itemize}
Issues:
\begin{itemize}
\item Nasty shell script
