A netlist is a text description of the circuit connectivity. It is basically a
list of connectors, a list of instances, and, for each instance, a list of the
signals connected to the instance terminals. In addition, the netlist
contains attribute information.
An NGA (native generic annotated) file is an output from the
NGDAnno run. An NGA file is subsequently input to the appropriate
NGD2 translation program.
The NGDAnno program distributes delays, setup and hold time, and
pulse widths found in the physical NCD design file back to the
logical NGD file. NGDAnno merges mapping information from the
NGM file, and timing information from the NCD file and puts all this
data in the NGA file.
The NGDBuild program performs all the steps necessary to read a
netlist file in XNF or EDIF format and create an NGD file describing
the logical design. The NGDBuild program executes as the Translate
step within the Flow Engine.
An NGD (native generic database) file is an output from the
NGDBuild run. An NGD file contains a logical description of the
design expressed both in terms of the hierarchy used when the design
was first created and in terms of lower-level Xilinx primitives to
which the hierarchy resolves.
An NGM (native generic mapping) file is an output from the MAP
run and contains mapping information for the design. The NGM file
is an input file to the NGDAnno program.
