Source File Requirements - XILINX (XACT) Devices

SOURCE FILE REQUIREMENTS - XILINX Devices
Using Xilinx XACT or Compatible software

XILINX source files must be provided for each device. These files will allow Test Software Systems to develop test vectors for in-circuit testing.

REQUIRMENTS

Source Files Required : .XNF

Design Software : Xilinx XACT Development Software,
Xilinx M1 Development Software, Or
Xilinx-compatible Design Software

Supported Families : XC2000, XC3000, XC4000, XC5000, XC7000, XC9500

DEFINITIONS

The .XNF file is a flattened XNF-style netlist file.

TECHNICAL INSTRUCTIONS to generate .XNF files using XACT or Xilinx-compatible design software

1. For Xilinx 2000, 3000, 4000, 5000, & 9500 devices, .XNF files must be created using the LCA2XNF utility. LCA2XNF converts Logic Cell Array (.LCA) files into Xilinx Netlist Format(.XNF) files. The LCA2XNF utility can be run either from the XACT Design Manager or a DOS command line.
If running XACT Design Manager, go to Convert menu,
Select LCA2XNF. Specify the .LCA file to be converted and select DONE.

If running from a DOS command line within the XACT directory, run:

LCA2XNF -g <filename.LCA>

NOTE: If the .LCA file was created using NeoCad software, include both the -v & -g switches on the LCA2XNF command line, as follows:

LCA2XNF -v -g <filename.LCA>

2. For Xilinx 7000 devices, .XNF files are created with the VMH2XNF utility, using the .VMH file, instead of the .LCA file, as input.
From the XACT Design Manager Verify menu, select VMH2XNF.
Specify the .VMH file to be converted and select DONE.

3. With Xilinx M1 software, .XNF files are created with the NGD2VNF utility using the .NGD file.

4. The resultant .XNF file should now be in the proper format and may be forwarded to TEST SOFTWARE SYSTEMS. Please include the associated component reference designator with the file.
