===============
To build Yosys simply type 'make' in this directory. 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. It might be necessary to make some changes to
the config section of the Makefile. The extensive tests require
Icarus Verilog.

To configure the build system to use a specific set of compiler and
build configuration, use one of
$ make config-clang-debug
$ make config-gcc-debug
$ make config-release
For other compilers and build configurations it might be
necessary to make some changes to the config section of the
Makefile.
$ vi Makefile
To build Yosys simply type 'make' in this directory.
$ make
$ make test
$ sudo make install
