Multi Pass PAR has problems in several versions of the tools.
Another option is using command-line and the -t option.
par ... -t n ...
where n is the seed.  Then you can have your own multi-pass
batch file that works the same as single pass.

Under MAP or PAR properties (right click) change the "Starting Placer
Cost Table (1-100)"

You could also try enabling Multi Pass PAR...

Hi,

I would like to know if there is a away to change the random seed used
by the Xilinx tools ?

I would like to do this in order to compare the results of multiple
place and routes.
