(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 HDLs - 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. {Specification (ftp://ftp.xilinx.com/pub/documentation/xactstep6/xnfspec.pdf)}. (1999-03-31)
