Degates' purpose is to aid in VLSI- reverse engineering of digital logic in integrated circuits (ICs). Degate helps you to explore images from ICs. It matches standard cells on the imagery given by graphical templates and to some degree vias and wires. Degate assists you in tracing circuit paths and in reconstructing the netlist.
Degate is not a completely automatic analyzing tool. Degate helps you with some automation in your manual reverse engineering process.
