10 years agoChecksum of the SOF file
When I download any sof file into the SRAM cells of the FPGA, in the programmer window there is a random checksum ID specific to some design. SOF file when edited using a textpad shows few english...

10 years ago1) No - you cannot read back the checksum. You cannot read back anything from the FPGA's configuration SRAM.
2) I doubt you can unless Altera publish how they calculate this. I'm not aware they do. 3) No - you certainly cannot reverse engineer a design purely from the checksum. 4) Configuration sizes for a particular device are always the same size (unless the particular FPGA family/device supports compressed configuration images. I'm a little troubled as to your motives for knowing these things... Cheers, Alex
