Migrating XBLOX designs to M1: XBLOX2M1 archive now exists on ftp site


Keywords: xblox, xblox2m1, conversion

Urgency: standard

General Description:

The M1 tools will not accept a XNF netlist that has unresolved XBLOX
symbols in it. The design should be either converted to use
LogiBLOX symbols (recommended), or the design must be run through
the XACT 5.2.x flow (XNFMERGE,XNFPREP, and XBLOX) to produce
the .xtf file (where XBLOX has been resolved into primitives),
which M1 will accept.

For more information on changing the design to use LogiBLOX
symbols, refer to the "Conversion Guide", located at:

(Xilinx File http://www.xilinx.com/txpatches/pub/documentation/M1/convergd_m1_4.pdf)



If you have XACT 5.2.x/6.0.x installed, and you are authorized
for XBLOX, then you may produce the .xtf file by either:

1) Running "xmake -n" (-n will cause xmake to halt upon producing
the .xtf file; otherwise PPR will execute)
2) On the PC, create a project in Design Manager (6.0.1)
and indicate within Flow Engine to stop after Trimming but before
3) Manually execute the steps:
xnfmerge <design.xnf>
xnfprep <design.xff>
xblox <design>
xnfprep <design.xg>


If you do not have XACT 5.2.x/6.0.x installed, or if you
have XACT 5.2.x/6.0.x but you are not licensed for
XBLOX, then you may download the "xblox2m1" archive
on our FTP site. This will contain the programs
XNFMERGE, XNFPREP, and a de-licensed version of
XBLOX, as well as all the supporting data files
required for these programs to execute.
This archive will also contain the scripts "xblox2m1"
and "xblox2m1.bat" (for Sun/HP and PC, respectively),
which will allow you to automate the translation to
.xtf (although you may run the individual steps yourself,
if you wish). Details of installation and usage are
included in the README.TXT file that comes with the
This archive does not contain XMAKE, XDM or Design Manager.

For the PC:
