Problem Title:
XNFBA error 301: Possible workaround


Problem Description:
First make sure you have the latest version on XNFBA (5.2.1). Also, please check
 (Xilinx Solution #495).
If you get XNFBA error 301, and Solution 495 does not help, you might try the fo
llowing.


Solution 1:

The workaround is to run xnfba twice; once with the .xtf file,
and once again with the .xff file (or .xg file if X-BLOX is
used). Note this is not guaranteed to work, although it has
been observed to solve the problem in several cases. Also
note that "xnfba" is not necessary; simply not running it
is perfectly valid, although you will not be able to probe
some internal nets.


For non-XBLOX designs:
-----------------------
lca2xnf design.lca
xnfba design.xtf design.xnf -o design.xnf
xnfba design.xff design.xnf -o design.xnf

continue with the normal flow...

For XBLOX designs:
-----------------------
lca2xnf -g design.lca
xnfba design.xtf design.xnf -o design.xnf
xnfba design.xg design.xnf -o design.xnf

continue with the normal flow...
