         (XNF) A {Hardware Description
        Language} for electronic circuit design, developed by {Xilinx,
        Inc.}.
     
        {Xilinx}-developed tools use XNF and handle the details of the
        {FPGA} architecture.  Converters are available for a number of
        widely-used {HDL}s - for example {Verilog} ({xnf2ver}) - so
        that designers can use familiar tools to develop Logic Cell
        Array designs.  In addition, XNF can be converted to the input
        language of different {logic simulators}.
