I realize that this might not be appropriate question for this group, but considering the level of knowledge I thought I would see if anyone knows much about recovering lost verilog code from a .sof altera Quartus FPGA binary? Some of the my companies IP cores source has disappeared and thought maybe someone here could help me out at recovering the missing source. Does anyone know of any altera dissassembler or decompiler for the SOF file? I'm not particularly concerned if the the output is VHDL, verilog, or even AHDL. Because of the ethics of reverse engineering I would be willing to present anyone with the evidence they might need to verify that my company has all copyrights and ownership of the .sof Im asking to derive the source code. Any thoughts how I can do this?
