This Application Note is based on the Yosys \cite{yosys} GIT Rev. {\tt 2b90ba1} from
2013-12-08. The {\tt README} file covers how to install Yosys. The
{\tt show} command requires a working installation of GraphViz \cite{graphviz}
for generating the actual circuit diagrams. Yosys must be build with Qt
support for the built-in SVG viewer. Alternatively an external viewer can be
used, if Qt is not available.

When called without any special options, it saves the circuit diagram in
a temporary file and launches {\tt yosys-svgviewer} to display the diagram.

Per default the {\tt show} command outputs a temporary {\tt dot} file and launches

Note that the {\tt pdf} and {\tt ps} format are the only formats that support
plotting multiple modules in one run.
In {\tt yosys-svgviewer} the left mouse button is per default bound to move the
diagram (and the mouse wheel can be used for zooming in and out). However, in
some cases one wants to copy text from the diagram. In this cases the
View->Interactive checkbox must be activated. This switches the rendering back-end
in a mode that supports interaction with the SVG file, such as selecting text.
In densely connected circuits it is sometimes hard to keep track of the
individual signal wires. For this cases it can be useful to call {\tt show}
with the {\tt -colors <integer>} argument, which randomly assigns colors to the

\section{yosys-svgviewer}
The {\tt yosys-svgviewer} tool is a small Qt program that can be used to view
SVG files. This tool is automatically launched by the {\tt show} command when
no {\tt -format} and no {\tt -viewer} option is passed to the command. See
{\tt help show} or Sec.~\ref{cmd:show} for details.
