ftjrev is a powerful JTAG reverse-engineering tool. When coupled with an FTDI based JTAG cable and connected to a target board, ftjrev can be used to extract a netlist of interconnections between JTAG enabled components. It is compatible with FT2232 based JTAG cables.
This version of ftjrev is a modified version of the one released by NSA@home.
