Getting Started

Setup
======
You need a C++ compiler with C++11 support (up-to-date CLANG or GCC is
recommended) and some standard tools such as GNU Flex, GNU Bison, and GNU Make.
TCL, readline and libffi are optional (see ``ENABLE_*`` settings in Makefile).
Xdot (graphviz) is used by the ``show`` command in yosys to display schematics.
For example on Ubuntu Linux 16.04 LTS the following commands will install all
prerequisites for building yosys:

libreadline-dev gawk tcl-dev libffi-dev git mercurial \
graphviz xdot pkg-config python3
Similarily, on Mac OS X MacPorts or Homebrew can be used to install dependencies:
$ brew install bison flex gawk libffi \
git mercurial graphviz pkg-config python3
$ sudo port install bison flex readline gawk libffi \
git mercurial graphviz pkgconfig python36
There are also pre-compiled Yosys binary packages for Ubuntu and Win32 as well
as a source distribution for Visual Studio. Visit the Yosys download page for
more information: http://www.clifford.at/yosys/download.html

Note that this also downloads, builds and installs ABC (using yosys-abc
as executable name).
Getting Started
===============
Yosys can be used with the interactive command shell, with
synthesis scripts or with command line arguments. Let's perform
a simple synthesis job using the interactive command shell:
