VSM 6.0 now writes out the format in a "compact" form by default.
In order to get to the old "compatible" format (their terminology), 
you must run VSM with the new -c option.  This keeps everything in 
the format that VSMUPD and other Xilinx tool expect.

XSIMMAKE calls VSM without this -C option, so a new file is required
to ammend this inconsistency.  The file is XSIMMAKE.XFW (it's a shell
that goes along with the XSIMMAKE.EXE executable), and the version is 
"5.2.1-PV60a", and included is a message in the version banner that 
states it is for Powerview 6.0 only.  It is to be run with version 
5.2.1 of the XACT core tools.  Note that it will not work with 
Workview Office or any earlier version of Powerview, since the -C 
option does not exist elsewhere at present.

For this xsimmake.xfw file to be used, it must be installed ahead of
the released version in the XACT environment variable path, or in the
current project directory when XSIMMAKE is run.  It must be placed in
a "data" directory in either case.

For example, if you place the new xsimmake.xfw file in
$HOME/pview/data/xsimmake.xfw, you will need to change your XACT variable
like this:

setenv XACT=$HOME/pview:<old_XACT_path>
