Xilinx Netlist Format
<language, electronics> (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.
