## yosys-0.9pl4081p4 – framework for Verilog RTL synthesis

## Description

    Yosys Open SYnthesis Suite

    Yosys is a framework for Verilog RTL synthesis. It currently has extensive
    Verilog-2005 support and provides a basic set of synthesis algorithms for
    various application domains. Selected features and typical applications:

    - Process almost any synthesizable Verilog-2005 design
    - Converting Verilog to BLIF / EDIF/ BTOR / SMT-LIB / simple RTL Verilog / etc.
    - Built-in formal methods for checking properties and equivalence
    - Mapping to ASIC standard cell libraries (in Liberty File Format)
    - Mapping to Xilinx 7-Series and Lattice iCE40 FPGAs
    - Foundation and/or front-end for custom flows

    Yosys can be adapted to perform any synthesis job by combining the existing
    passes (algorithms) using synthesis scripts and adding additional passes as
    needed by extending the Yosys C++ code base.
