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.
|
||||
The Qt4 library is needed for the yosys SVG viewer, that is used to display
|
||||
schematics, the minisat library is required for the SAT features in yosys
|
||||
and TCL for the scripting functionality. The extensive test suite requires
|
||||
Icarus Verilog. For example on Ubuntu Linux 12.04 LTS the following commands
|
||||
will install all prerequisites for building yosys:
|
||||
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 14.04 LTS the following commands will install all
|
||||
prerequisites for building yosys:
|
||||
|
||||
$ yosys_deps="git g++ clang make bison flex libreadline-dev
|
||||
tcl8.5-dev zlib1g-dev libqt4-dev libffi-dev

tcl8.5-dev libffi-dev git mercurial graphviz xdot"
