FPGA netlist from Bitstream
 

Hi everyone,

can someone help me out in reversing an fpga bitstream?
Does anyone have knowledge in this filed?

It is an artix7 bitstream with picoblaze and microblaze softcore. I am trying to extract the code for these.
Would also be nice to get a netlist or a verilog file back from the bitstream, but seems impossible.

Best wishes

Did you see these FPGA bitstream reversing presentations already?

You can find info at this github:

or to "fpgadeveloper.com":

Thank you all for the links.

I do have an extracted microblaze binary now.
I can disassemble no problem but there is no decompiler I could find.
I will open a new thread for that.

thx
