Default BIT files

Sorry - newbie here so not the most brain draining question. I want to test
if a previous design works on a board that I have. The previous design was
done for a similar board. What I want to know - Can I just take the .bit
file and send it down via IMPACT? That way eliminating any Xilinx different
version conflict between my software and the software it was designed on?
Basically to see if this design is working fine on my board - a previously
simulated and synthesized .bit file ONLY is all I need to demonstrate the
working project fully????

Regards

D

How similar?

Generally, the bit file has to be originally generated for the same Xilinx
device in the same package and your board should be using the same pins. If
the device is different IMPACT will probably simply refuse to load the file,
which is not more than a frustration. If, however, your new board uses pins
differently you might end up having to deal with a much bigger problem.

P.S. This question has nothing to do with comp.lang.vhdl, so I am not
replying there...
