Yosys

Table Of Contents

Auxiliary Programs

Besides the main yosys executable, the Yosys distribution contains a set of additional helper programs.

yosys-config

The yosys-config tool (an auto-generated shell-script) can be used to query compiler options and other information needed for building loadable modules for Yosys. FIXME: See Sec. [chapter:prog] for details.

yosys-filterlib

The yosys-filterlib tool is a small utility that can be used to strip or extract information from a Liberty file. See Sec. [sec:techmap_extern] for details.

yosys-abc

This is a fork of ABC with a small set of custom modifications that have not yet been accepted upstream. Not all versions of Yosys work with all versions of ABC. So Yosys comes with its own yosys-abc to avoid compatibility issues between the two.
