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.

For more information on the history and usage of ftjrev, please visit the page on JTAG Reverse Engineering.
