Crack Lattice CPLD Embeded Firmware from its memory, copy jed content to blank Lattice CPLD which will provide the same functions as original master CPLD, this microcontroller security unlocking technique can help engineer to extract jed file from master CPLD.
Reverse engineering is a technique aimed at understanding the structure of a semiconductor device and its functions. In case of an ASIC or a custom IC, that means extracting information about the location of all the transistors and interconnections. In order to succeed, a general knowledge of IC and VLSI design is required.
All the layers formed during chip fabrication are removed one-by-one in reverse order and photographed to determine the internal structure of the chip. In the end, by processing all the acquired information, a standard netlist file can be created and used to simulate the device. This is a tedious and time-consuming process, but there are some companies, for example Chipworks [110], which do such work as a standard service.
