FPGA configuration file

[bansalr]

Hi,
I have a doubt regarding the FPGA configuration file is this remain fix irrespective of the Logic utilization.
I assume i to be fixed.

Any comments or supporting docs are welcome

yes length is fixed

so u mean to say something like this

say my conf. file size is 512kb and is it independent of logic in fpga...

like if we open tht file in word we can see 1's n 0's n some part is full of 0's...so when we add new logic in fpga, now in tht file the 0th part will be filled accrdingly... am i right?

For Xilinx, if you use a small amount of FPGA logic, then the configuration file will be mostly zeros. If you use lots of logic, then the configuration file looks more like a random assortment of zeros and ones. I haven't tried Altera, but the results may be similar.

in altera tht is hexout file

but pof and sof file has random characters....
