2 \chapter{Auxiliary Programs
}
4 Besides the main
{\tt yosys
} executable, the Yosys distribution contains a set
5 of additional helper programs.
9 The
{\tt yosys-config
} tool (an auto-generated shell-script) can be used to
10 query compiler options and other information needed for building loadable
11 modules for Yosys. FIXME: See Sec.~
\ref{chapter:prog
} for details.
13 \section{yosys-filterlib
}
16 The
{\tt yosys-filterlib
} tool is a small utility that can be used to strip
17 or extract information from a Liberty file. See Sec.~
\ref{sec:techmap_extern
}
22 This is a unmodified copy of ABC
\citeweblink{ABC
}. Not all versions of Yosys
23 work with all versions of ABC. So Yosys comes with its own yosys-abc to avoid
24 compatibility issues between the two.
