Hello,
against the background of partial reconfiguration, I would like to=20 determine the difference between two initial configurations (NCDs). Does =
any Xilinx tool support this?

You are probably looking for $ bitgen version1.ncd version1.bit $ bitgen -r version1.bit version2.ncd diff1to2.bit

Or if you are really brave, maybe
$ xdl -ncd2xdl file1.ncd $ xdl -ncd2xdl file2.ncd
$ diff -u file1.xdl file2.xdl
Note I've never tried this, it could well produce garbage, depending on how "repeatable" is the output of ncd2xdl.
Cheers,
John
Ok, I have forgotten to say, it should be human readable.

Apart from the graphical representation given by fpga_editor, I think xdl is the only human readable form of the NCD database.
Did you try the "diff -u" on two xdl files? I'm really curious to see if you get meaningful output. XDL contains all of the mapping, placement, routing, everything, in text format, so in principle it should be possible.
