We have a customer who has an old version of source code for the above FPGA and an updated bitstream. We need to generate the delta source code so that development progress can continue with the product. Is there any tool or assistance available to enable a bitstream to be reverse engineered to achieve this? We do have an earlier source for it for reference
No, We don't have any tool for generating the source file from a binary file.
We need the source file to update and generate a binary file and program FPGA.
