Default Bitfile checking

Assuming a scenario that I have a bit file built for a particular
FPGA, but i don't have a that FPGA device to download it to, Is there
a way to check it works on that particular FPGA?

Thanks in advance
Water

I think he can do it with HTVS*. You just check that it looks good on
paper, then ship it.

I'm not sure that I would answer no to this universally.

The bitstream format should enable you to determine if was made for
a Xilinx, Altera or Lattice device. In the case of Xilinx devices, you
should also be able to determine what family and die it was intended for,
but not the package, by parsing the bitstream and looking for specific
fields. Even, the bitstream file size itself should be a good indicator
of what device it should work.

Now, whether or not it actually works is a completely different question.

Ed the OP wanted to VERIFY device operation using bitstream and no
device.

so he wants a SIMULATOR that can load bistream
those are not generically available ASFAIK

Antti,

If I was a lawyer I would respond with "assuming facts not in evidence".
Was there another thread on this subject that I missed?

LOL, eh yes it depends on "it works" ...

if we assume a bitstream for a given FPGA always works on the given
FPGA then its sufficient to look file header
if we assume "it works" as it functions as expected, then well we most
certainly need the FPGA and target system and load the bitstream

but a FPGA BITFILE simulator would be funny toy
